A numerical study of long-term multi-wavelength blazar variability
M. Polkas, M. Petropoulou, G. Vasilopoulos +4
Decade-long monitoring of blazars at optical and infrared (OIR) wavelengths with the Small and Moderate Aperture Research Telescope System (SMARTS) in Chile and in -rays with th…
The eROSITA Final Equatorial-Depth Survey (eFEDS): Identification and characterization of the counterparts to the point-like sources
M. Salvato, J. Wolf, T. Dwelly +41
In November 2019, eROSITA on board of SRG observatory started to map the entire sky in X-rays. After the 4-year survey program, it will reach flux limits about 25 times deeper than…
Properties of the Obscuring Torus in NGC 1052 from Multi-epoch Broadband X-ray Spectroscopy
M. Baloković, S. E. Cabral, L. Brenneman +1
Obscuration of the innermost parts of active galactic nuclei (AGN) is observed in the majority of the population both in the nearby universe and at high redshift. However, the natu…
NuSTAR Survey of Obscured Swift/BAT-selected Active Galactic Nuclei: II. Median High-energy Cutoff in Seyfert II Hard X-ray Spectra
M. Baloković, F. A. Harrison, G. Madejski +16
Broadband X-ray spectroscopy of the X-ray emission produced in the coronae of active galactic nuclei (AGN) can provide important insights into the physical conditions very close to…
Physical Inference from the gamma-ray, X-Ray and Optical Time Variability of a Large Sample of Fermi Blazars
Anwesh Majumder, Kaustav Mitra, Ritaban Chatterjee +3
We present cross-correlation studies of gamma-ray (0.1-300 GeV), X-ray (0.2-10 keV) and optical (R-band) variability of a sample of 26 blazars during 2008-2016. The light curves ar…
BAT AGN Spectroscopic Survey: XVI. General Physical Characteristics of BAT Blazars
Vaidehi S. Paliya, M. Koss, B. Trakhtenbrot +12
The recently released 105-month {\it Swift}-Burst Alert Telescope (BAT) all-sky hard X-ray survey catalog presents an opportunity to study astrophysical objects detected in the dee…
