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…
Transient QPOs of Fermi-LAT blazars with Linearly Multiplicative Oscillations
P. Penil, J. Otero-Santos, A. Circiello +5
We present a study on the detection and characterization of transient quasi-periodic oscillations (QPOs) in the -ray emission of blazars 4C +31.03, MG1 J123931+0443, and PKS 16…
Discovering High- BL Lacs Using Swift/UVOT and SARA Observations with the Dropout Technique
Y. Sheng, K. Imam, A. Kaur +14
Measuring spectroscopic redshifts for BL Lacertae (BL Lac) objects, a class of blazar, is challenging because their optical spectrum lacks, or has weak, emission lines ( equivalent…
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…
Evaluating the Potential to Constrain Dark Matter Annihilation with Fermi-LAT Observations of Ultra-Faint Compact Stellar Systems
A. Circiello, A. McDaniel, A. Drlica-Wagner +4
Recent results from numerical simulations and models of galaxy formation suggest that recently discovered ultra-faint compact stellar systems (UFCSs) in the halo of the Milky Way (…
