MeV dark matter decay forecasts for the COSI mission

Robin Anthony-Petersen, Orion Ning, Yu Watanabe +21

The decay of dark matter (DM) is a generic prediction of many particle physics models, producing distinctive monochromatic signatures in environments such as the Galactic halo. Sea…

Legacy analysis of Milky Way dwarf spheroidal satellite galaxies: an update

A. Circiello, M. Di Mauro, M. Ajello +3

Studies of Fermi-Large Area Telescope (LAT) data coincident with dwarf spheroidal satellite galaxies (dSphs) of the Milky Way (MW) have put the most stringent constraints on models…

Detectability of Polarized Gamma-ray Emission from Blazar Flares with COSI

Garrett A. Latiolais, Jorge Otero-Santos, Michela Negro +18

We investigate the detectability of polarized gamma-ray emission from blazar flares with the Compton Spectrometer and Imager (COSI). Using 17 years of Fermi Large Area Telescope ob…

Characterizing the Gamma-ray Emission from Low-Luminosity AGN

Chris Karwin, Nikita Khatiya, Margot Boughelilba +3

A majority of the active galactic nuclei (AGN) in the local Universe are classified as low-luminosity AGN (LLAGN), having bolometric luminosities $\lesssim 10^{42} \ \mathrm{erg \…

The gamma-ray emission from Radio Galaxies and their contribution to the Isotropic Gamma-Ray Background

A. Circiello, A. McDaniel, M. Di Mauro +6

We evaluate the contribution to the Isotropic Gamma-Ray Background (IGRB) coming from Radio Galaxies (RGs), the subclass of radio-loud Active Galactic Nuclei (AGN) with the highest…

Pre-flight Background Estimates for COSI

Savitri Gallego, Uwe Oberlack, Jan Lommler +14

The Compton Spectrometer and Imager (COSI) is a Compton telescope designed to survey the 0.2 - 5 MeV sky, consisting of a compact array of cross-strip germanium detectors. It is pl…
