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…

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…

Multi-wavelength observations of a jet launch in real time from the post-changing-look Active Galaxy 1ES 1927+654

Sibasish Laha, Eileen T. Meyer, Dev R. Sadaula +34

We present results from a high cadence multi-wavelength observational campaign of the enigmatic changing look AGN 1ES 1927+654 from May 2022- April 2024, coincident with an unprece…

A Multi-Wavelength Characterization of the Obscuring Medium at the Center of NGC 6300

D. Sengupta, N. Torres-Albà, A. Pizzetti +9

Most of the super-massive black holes in the Universe accrete material in an obscured phase. While it is commonly accepted that the "dusty torus" is responsible for the nuclear obs…

Hydrogen Column Density Variability in a Sample of Local Compton-Thin AGN II

A. Pizzetti, N. Torres-Alba, S. Marchesi +7

We present the multi-epoch analysis of 13 variable, nearby (z<0.1), Compton-thin (22<logN_H<24) active galactic nuclei (AGN) selected from the 105-month BAT catalog. Analyzing all…
