An XMM-Newton Analysis of the Supermassive Black Hole Binary Candidate MCG+11--11--032

Yash A. Gursahani, Tingting Liu, Richard Mushotzky +2

We investigate the possibility of a binary supermassive black hole system at the center of MCG+11--11--032, a local (z = 0.036) Seyfert 2 galaxy. Prior work with stacked Swift/XRT…

An outflow from the X-ray corona as the origin of millimeter emission from radio-quiet AGN

A. Hankla, A. Philippov, R. Mbarek +4

Recent observations of radio-quiet active galactic nuclei (RQAGN) have shown the presence of millimeter emission, whose origin remains unknown, from within parsec scales of the cen…

ALMA discovery of Punctum -- a highly polarized mm source in nuclear starburst galaxy NGC 4945

E. Shablovinskaia, C. Ricci, C-S. Chang +9

We report the discovery of a highly polarized millimeter (mm) continuum source in the central region of NGC 4945, identified through ALMA Band 3 observations. This starburst Seyfer…

XRISM Spectroscopy of Accretion-Driven Wind Feedback in NGC 4151

Xin Xiang, Jon M. Miller, Ehud Behar +17

The hottest, most ionized, and fastest winds driven by accretion onto massive black holes have the potential to reshape their host galaxies. Calorimeter-resolution X-ray spectrosco…

XRISM analysis of the complex Fe K line in Centaurus A

David Bogensberger, Yuya Nakatani, Tahir Yaqoob +14

We analyze the high-resolution XRISM/Resolve spectrum of the Fe K emission line of the nearest active galactic nucleus, in Centaurus A. The line features two narrow and resolved…

Superluminal proper motion in the X-ray jet of Centaurus A

David Bogensberger, Jon M. Miller, Richard Mushotzky +4

The structure of the jet in Cen A is likely better revealed in X-rays than in the radio band, which is usually used to investigate jet proper motions. In this paper, we analyze Cha…
