Supermassive Black Hole Winds in X-rays -- SUBWAYS. VI. Interplay between the soft X-ray excess and ultra-fast outflows
V. E. Gianolli, P-O. Petrucci, S. Bianchi +42
We present a broadband, multiwavelength study of the interplay between the soft X-ray excess (SE), ultra-fast outflows (UFOs), and warm absorbers (WAs) in 21 active galactic nuclei…
Source identification for the Swift-BAT 150-month hard X-ray catalog using soft X-ray observations
K. Imam, N. Torres-Alba, S. Marchesi +10
We present a comprehensive catalog of 251 potential counterparts for 250 unassociated hard X-ray sources detected in the Swift Burst Alert Telescope (BAT) 150-month hard X-ray surv…
Unveiling Obscured Accretion in the Local Universe
Indrani Pal, Stefano Marchesi, Ross Silver +9
Heavily obscured Active Galactic Nuclei (AGN), especially Compton-thick sources with line-of-sight column density () 10 cm, are critical to underst…
A multi-wavelength view of the multi-messenger sources NGC 1068 and PKS 1502+1061
Abhishek Desai, Stefano Marchesi, Justin Vandenbroucke +8
Multi-messenger astronomy offers a powerful approach to studying high-energy radiative processes in astrophysical sources. A notable example was seen in 2017, when the IceCube Neut…
Contemporaneous X-ray and Optical Polarization of EHSP Blazar H 1426+428
Anuvab Banerjee, Akash Garg, Divya Rawat +17
We present the first contemporaneous X-ray and optical polarimetric measurement of the extremely high synchrotron peaked (EHSP) blazar H 1426+428. The X-ray polarimetric observatio…
X-ray polarization observations of NGC 2110 with IXPE
I. Pal, S. Marchesi, N. Torres-Albá +6
X-ray polarimetric observations from the Imaging X-ray Polarimeter Explorer (IXPE) is an excellent tool for probing the geometry and dynamics of X-ray emitting corona in active gal…
Swift-XRT and NuSTAR Monitoring of Obscuration Variability in Mrk 477
N. Torres-Albà, Z. Hu, I. Cox +6
We present the analysis of 15 X-ray observations of Mrk 477, a nearby Seyfert 2 active galactic nucleus, with the objective to monitor its obscuring column density variability. The…
