Classifying blazar candidates from the 3FGL unassociated catalog into BL Lacs and FSRQs using Swift and WISE data
Amanpreet Kaur, Abraham D. Falcone, Michael C. Stroh
We utilize machine learning methods to distinguish BL Lacertae objects (BL Lac) from Flat Spectrum Radio Quasars (FSRQ) within a sample of likely X-ray blazar counterparts to Fermi…
Identifying the 3FHL Catalog. IV. Swift Observations of Unassociated Fermi-LAT 3FHL Sources
Ross Silver, Stefano Marchesi, Lea Marcotulli +3
The Fermi Large Area Telescope (Fermi-LAT) 3FHL catalog is the latest catalog of >10 GeV sources and will remain an important resource for the high-energy community for the foresee…
Blazars at the Cosmic Dawn
Vaidehi S. Paliya, M. Ajello, H. -M. Cao +5
The uncharted territory of the high-redshift () Universe holds the key to understand the evolution of quasars. In an attempt to identify the most extreme members of the…
Hunting distant BL Lacs with the photometric technique using Swift and SARA
M. Rajagopal, A. Kaur, A. Ajello +5
BL Lacertae objects (BL Lacs) represent a large fraction (22\%) of gamma-ray sources in the Third Fermi Large Area Telescope catalog (3FGL). Nearly half of the BL Lac population re…
NuSTAR Observations and multi-wavelength modeling of the high-redshift BL Lac Object 4FGL J2146.5-1344
M. Rajagopal, L. Marcotulli, M. Ajello +3
High synchrotron peak (HSP; Hz) BL Lacs are some of the most extreme accelerators in the Universe. Those found at high redshifts () challenge our under…
NuSTAR perspective on high-redshift MeV blazars
L. Marcotulli, V. Paliya, M. Ajello +7
With bolometric luminosities exceeding erg s, powerful jets and supermassive black holes at their center, MeV blazars are some of the most extreme sources in the U…
