May 13, 2019AGILE prompt follow-up of the LIGO/Virgo GW trigger event S190512at

In response to the public LIGO/Virgo gravitational wave (GW) alert of the on-going osservative run O3, with trigger event name S190512at at T0 = 2019-05-12 18:07:14.422 (UT), the AGILE Team performed a quick look follow-up analysis of the AGILE data. The AGILE satellite at T0 was in the South Atlantic Anomaly (SAA), and the S190510g Ligo-Virgo 90% c.l. localization region was occulted by the Earth.

Preliminary MCAL results and AGILE GRID upper limits in the first time intervals available after the SAA have been published in two GCN CIRCULARS:
GCN #24507: LIGO-Virgo S190512at: AGILE MCAL observations (A. Ursi et al.)
GCN #24519: LIGO-Virgo S190512at: AGILE GRID observations (C. Pittori et al.)

May 10, 2019AGILE prompt follow-up of the LIGO/Virgo GW trigger event S190510g

In response to the public LIGO/Virgo gravitational wave (GW) alert of the on-going osservative run O3, with trigger event name S190510g at T0 = 2019-05-10 02:59:39 (UT), the AGILE Team performed a quick look follow-up analysis of the AGILE data.
The AGILE exposure at T0 shows that the S190510g Ligo-Virgo localization region was covered by the MCAl instrument for about 90%, and by the GRID instrument for about 60%.

Apr 03, 2019The new AGILE-GRID Catalog: 2AGL

We are pleased to announce that "The Second AGILE Catalog of Gamma-Ray Sources" (A. Bulgarelli et al., 2019), arXiv:1903.06957, has been accepted for publication in Astronomy & Astrophysics. The new 2AGL incorporates several analysis improvements, including better calibrations, an updated model for the Galactic diffuse gamma-ray emission, and the inclusion of a search for extended gamma-ray sources. The 2AGL Catalog includes 175 high-confidence sources, with a sub-class of 29 "AGILE only" gamma-ray sources that are not present in 1FGL, 2FGL or 3FGL Fermi catalogs.

An on-line version of the new 2AGL Catalog, plus some supplementary information, including AGILE skymaps, is now available as an interactive web table at SSDC.

After the paper publication on A&A, a new version of the 2AGL webpage (V2.0) at SSDC will also give access to other AGILE data products, such as spectra and light curves.

Jan 15, 2019New AGILE Public Data Now Available

We are pleased to announce the publication of new AGILE gamma-ray data up to November 30, 2018.
Since December 28, 2018, the new public AGILE archive now contains all data from December 1, 2007 up to November 30, 2018,i.e. from the start of Cycle-1 up to the end of Cycle-11. AGILE-GRID event files (EVT) and spacecraft auxiliary (LOG) files are available from the SSDC Multimission Archive (MMIA) webpage for the AGILE Mission.

We recall that since October 2015 all AGILE-GRID data are published as soon as they are processed and validated. The new AGILE Cycle-11 data were obtained with AGILE observing a large portion of the sky in spinning mode, and they have been processed with the latest available software and calibrations. AGILE satellite operations and all AGILE payload functions are nominal.

For an easy on-line AGILE data analysis, the interested user may also query the entire public AGILE level 3 (LV3) archive through the AGILE-LV3 data analysis tool. The AGILE-LV3 web tool is meant to be easily comprehensible, and it does not require any installed software or calibrations. We also plan to update the underlying AGILE software and calibrations in the next few months. Stay tuned!

Nov 05, 2018NASA Dawn mission ends after 11 years

NASA Dawn mission, the first one to explore two different objects of the main asteroid belt (Vesta and Ceres), ended few days ago after missing two scheduled communication sessions with NASA's Deep Space Network on Wednesday, Oct. 31, and Thursday, Nov. 1.

The mission lasted 11 years and, among its precious scientific results, those regarding the composition of Vesta, that has been confirmed as the parent body of the HED meteorites and the discovery of a large carbonates deposit forming a peculiar bright spot inside the Occator crater of Ceres can be cited.

SSDC contributions to Dawn are twofolds: the availability of the VIR imaging spectrometer data through the MATISSE tool, and the participation of Marco Giardino (SSDC ITC Manager) to the mission Dawn Archive Working Group.

The VIR-Dawn data available through MATISSE have been also used for educational purposes, an activity now part of the curriculum of the "Introduction to Modern Astro-Plasma Physics" course of the East Windsor Regional School District in Hightstown, NJ (USA).

Oct 10, 2018SSDC interactive analysis tools among US Students: an american public school pioneer project

As part of the collaborative efforts with SSDC, Dr. Franco Paoletti incorporated two remote space data analysis activities in the curriculum of the "Introduction to Modern Astro-Plasma Physics" course, recently approved by the Board of Education of the East Windsor Regional School District in Hightstown, NJ (USA).

The two activities will see students analyzing data coming from both Solar System exploration and high-energy observations of the Universe, and will be performed using the SSDC interactive online analysis tools: MATISSE for Solar System observations and AGILE-LV3 for the gamma-ray AGILE satellite data.

The activities point to reproduce published scientific results, such as the characterization of dark material on the Vesta asteroid (e.g. Palomba et al., 2014) and the analysis of a couple of exceptional bright flares seen in gamma-rays from monster black holes in distant galaxies (e.g. Astronomer's Telegrams: ATel #9186 and ATel #7631).

The final goal is to provide the students with knowledge, skills, and competences required to correctly use tools specifically designed at our data center for professional researchers, and to get a better understanding of the day to day work of an astrophysicist.

Jun 21, 2018New AGILE Public Data now available up to May 31, 2018

We announce the publication of new AGILE gamma-ray data. The public AGILE archive now contains all data from December 1, 2007 to May 31, 2018, i.e. from the start of Cycle-1 up to the on-going Cycle-11. AGILE-GRID event files (EVT) and spacecraft auxiliary (LOG) files are available from the SSDC Multimission Archive (MMIA) webpage for the AGILE Mission.

We recall that, starting from October 2015 the standard one-year proprietary period was eliminated, and all AGILE-GRID data are now published as soon as they are processed and validated. The new public AGILE Cycle-11 data were obtained with AGILE observing a large portion of the sky in spinning mode, and they have been processed with the latest public software and calibrations.

For an easy on-line AGILE data analysis, we recall that the interested user may also query the entire public AGILE level 3 (LV3) archive through the AGILE-LV3 data analysis tool.

Jun 11, 2018MATISSE v1.5 online with a better 3D online visualization method

A new version of MATISSE (https://tools.ssdc.asi.it/matisse.jsp) has been released, with the major update regarding the 3D online visualization method.
Thanks to the use of a new javascript (https://kitware.github.io/vtk-js/) it is now possible to directly view online the 3D high-resolution models for the great part of the MATISSE targets, including the comet 67P, Vesta, Ceres and Venus, thus overtaking the limitation for larger objects present with the previous technology used.
This version has been labeled v1.5 and comes after the implementation of the SAMP protocol to interoperate with VESPA datasets (v1.3) and the addition of the 1 and 2 micron spectral parameters for VIR-Dawn observations of Vesta (v1.4).
