Radio Emission from Broad Absorption Line Quasars

Sina Chen, Ehud Behar, Ari Laor +1

Broad Absorption Line Quasars (BALQs) generally exhibit significant outflows that may interact with the surrounding medium, resulting in radio emission. We selected a sample of 13…

Detection of millimeter-wave coronal emission in a quasar at cosmological distance using microlensing

M. Rybak, D. Sluse, K. K. Gupta +5

Determining the nature of emission processes at the heart of quasars is critical for understanding environments of supermassive black holes. One of the key open questions is the or…

AGN STORM 2: X. The origin of the interband continuum delays in Mrk 817

Hagai Netzer, Michael R. Goad, Aaron J. Barth +26

The local (z=0.0315) AGN Mrk 817, was monitored over more than 500 days with space-borne and ground-based instruments as part of a large international campaign AGN STORM 2. Here, w…

A dichotomy in the 1-24 GHz parsec-scale radio spectra of radio-quiet quasars

Sina Chen, Ari Laor, Ehud Behar +3

We present the pc-scale radio spectra of a representative sample of 13 Palomar-Green radio-quiet quasars, based on our new Very Long Baseline Array (VLBA) observations at 8.4 and 2…

Windy or not: Radio pc-scale evidence for a broad-line region wind in radio-quiet quasars

Sina Chen, Ari Laor, Ehud Behar +6

Does a broad-line region (BLR) wind in radio-quiet (RQ) active galactic nuclei (AGN) extend to pc scales and produce radio emission? We explore the correlations between a pc-scale…

Supermassive Black Hole Winds in X-rays -- SUBWAYS. III. A population study on ultra-fast outflows

V. E. Gianolli, S. Bianchi, P-O Petrucci +44

The detection of blue-shifted absorption lines likely associated with ionized Iron K-shell transitions in the X-ray spectra of many Active Galactic Nuclei (AGN) suggests the presen…
