Jul 22, 2022AGILE news

AGILE, PUBLISHED THE FIRST ARTICLE ABOUT THE "NEW YEAR'S BURST"

The first article about the GRB 220101A, the exceptionally energetic "New Year's Burst", has been published by AGILE on July, 15, 2022 (Ursi et al., ApJ 933, 2022).

Few hours after the midnight of January 1, 2022, several satellites devoted to high-energy astrophysics, including AGILE had greeted the beginning of the new year by revealing what is probably the most energetic Gamma-Ray Burst (GRB) ever reported in the history of the observations of these phenomena, i.e., the GRB 220101A.

In its 15 years activity, AGILE has already had the opportunity to reveal some particularly intense GRBs, such as the GRB 080916C and the GRB 160625B, but these events are quite rare. GRB 220101A took place more than 12 billion light years away, at the time when the Universe was just about 1.3 billion years old, and its equivalent isotropic energy is the highest ever reconstructed for a GRB.

This record-breaking energy has drawn a great deal of attention from the scientific community in a short time. In the following days, more than twenty GCN communications were released, reporting observations carried out by other space missions and by astronomical ground-based observatories.

AGILE data provide a first characterization of the prompt phase of this GRB, which corresponds to the emission of high-energy radiation in the initial shocks taking place within the central engine. The different detectors onboard the satellite, whose energy coverage ranges from the X-ray (SuperAGILE 20-60 keV) to the gamma-ray (AGILE-MCAL 0.4-100 MeV) band, allowed to provide a first comprehensive overview of the temporal evolution and the energetics of this event. Using AGILE data together with public data from the Swift satellite, it was also possible to study also the so-called "afterglow" emission, that is, the delayed emission at lower energies, produced by the interactions of the initial shocks with the surrounding interstellar medium. This analysis allows to obtain interesting information regarding the environment in which such energetic event took place.


NEW AGILE TGF CATALOG UPDATE UP TO DECEMBER 31, 2021

AGILE confirms itself as an exceptional instrument, not only for the observation of cosmic phenomena, but it continues to give fundamental contribution also for the observation of high-energy phenomena from the Earth, such as the Terrestrial Gamma-Ray Flashes (TGFs) (A. Lindanger et al. 2020; C. Maiorana et al. 20209). Recently all TGFs seen by AGILE up to 31 December 2021 have been published as an interacting SSDC web page, including details and additional information compared to the original publications of the third TGF catalog in 2020.

Jun 06, 2022Paper about SSDC activities for LICIACube published

A paper describing the role of SSDC in the LICIACube mission has been recently published on the Planetary Science Journal.

Led by Angelo Zinzi, coordinator of Solar System Exploration activities in SSDC, the paper focuses on the preparation of the mission Science Operations Center (SOC), hosted and managed by SSDC.

The LICIACube SOC is in charge of processing and archiving the data. Raw images will be calibrated using algorithms developed by INAF. Both raw and calibrated images will be archived following the PDS4 standard, so that, after the proprietary period lasting 9 months from the DART impact on Dimorphos, they can be publicly released straightaway.

The paper also describes how the SSDC MATISSE webtool is being adapted to fully exploit LICIACube images, main changes including new geological functionalities and a new thermophysical model, best suited for small, rubble-pile asteroids.

Mar 09, 2022Mercury NASA MESSENGER's images on MATISSE

Last week an update on the MATISSE webtool, made it possible to search and retrieve calibrated images from the NASA MESSENGER MDIS-NAC camera using the NASA ODE REST protocol.
This is a crucial addition, taken into account the thermophysical model already available for Mercury and the work on the geological units planned to be released in the next months.
All these new functionalities could be of major interest for the study of Mercury, in preparation for the ESA-JAXA BepiColombo mission, presently on its way to starting orbiting the planet in 2025, making MATISSE a useful tool for data exploitation.

Feb 08, 2022The Second AGILE-MCAL GRB Catalog: 13 years of observations

We are pleased to announce that "The Second AGILE MCAL Gamma-Ray Burst Catalog: 13 yr of Observations" has been published in the Astrophysical Journal: A. Ursi et al., ApJ 925 (2022).

This new catalog presents the results of a systematic search and analysis of Gamma-Ray Burst (GRBs) detected by the Astrorivelatore Gamma ad Immagini LEggero (AGILE) MiniCALorimeter (MCAL) in the energy band 0.4–100 MeV, over a time frame of 13 years, from November 2007 to November 2020. The MCAL GRB sample consists of 503 bursts triggered by MCAL, 394 of which were fully detected onboard with high time resolution. The sample consists of about 44% short GRBs and 56% long GRBs.

The AGILE MCAL GRB sample in the new catalog mostly consists of hard-spectrum GRBs, with a large fraction of short-duration events. The MCAL bursts details can be used to perform joint broad-band analysis with other missions, and to provide insights on the high-energy component of the prompt emission in the tens of mega electron volt energy range.

An on-line version of the 2nd AGILE MCAL GRB Catalog is also available as an interactive web table at SSDC. The interactive webpage offers access to supplementary AGILE data products, such as: GRB MCAL lightcurves over 4 different timescales, hardness ratios, AGILE ratemeters lightcurves, and T50 and T90 lightcurve estimates.
For each event, the available supplementary data products can be visualized through the SSDC “GRB Explorer” tool.

Jan 31, 2022SSDC MATISSE at the Mercury Exploration Assessment Group Annual Meeting 2022

Helding in virtual form from 1st to 3rd February 2022, this year's Mercury Exploration Assessment Group (MExAG) Annual Meeting will view the participation of the SSDC Solar System Group presenting the current state and planned evolutions of the scientific webtool MATISSE related to Mercury exploration.
The agenda of the meeting includes an overview of NASA programs, ongoing science of the innermost planet, updates on ongoing concepts for future spacecraft missions, discussion of the MExAG Goals Document for the future of Mercury science and exploration.
For SSDC Angelo Zinzi will present a poster in which the focus of SSDC to the exploration of Mercury will be highlighted as up to now a thermophysical model is available through MATISSE, whereas the group is working to add observations (from NASA's MESSENGER MDIS-NAC) and semantic information (geological maps).

The SSDC interest in Mercury exploration is also demonstrated by the recent publication of a work by Edoardo Rognini focused on the effects of its surface temperatures on the exosphere composition.

The CHEOPS Science Workshop VI is currently ongoing, from January 11 to 13 2022 (https://cheops.unibe.ch/scienceworkshop2021).
Its main goal is to be the occasion for the planetary science community at large to discuss and review the main results obtained by CHEOPS after the first two years of scientific operations.

CHEOPS is the ESA missions, launched on December 2019 and dedicated to study bright, nearby stars already known to host exoplanets, to improve the system knowledge through high-precision observations of the planet's size.

SSDC is involved in the mission for what regards the set up and maintainance of the unique Scientific Archive mirror, available at: https://cheops-archive.ssdc.asi.it/archive_browser/

Sep 10, 2021Updated online version of the 3rd AGILE TGF Catalog, including events up to October 31, 2020

We announce that the SSDC online version of the 3rd AGILE Terrestrial Gamma-ray Flashes (TGF) Catalog, initially including events detected by the Minicalorimeter (MCAL) during the period March 2015 - September 2018 (A. Lindanger et al. 2020 and C. Maiorana et al. 2020), has been recently updated to include 517 new events associated with lightning sferics detected from October 1, 2018 to October 31, 2020. The total number of AGILE TGF events associated with lightning sferics from March 2015 to October 2020 is more than a thousand (1116).
The complete SSDC AGILE TGF web table is available here, and it also gives access to the available TGF light curves and counts details, providing supplementary material to the published papers. The current version, published online on September 2, 2021 also includes minor bug fixes affecting the previous plotting of some of the TGF lightcurves during the so-called DRIFT period (see references for more details).
