Extended [CII] gas emission in and around a massive quiescent galaxy at z=7.3

F. Valentino, A. Pensabene, A. Weibel +16

We report the discovery of [CII] 158 micron emission in and around the most distant known massive quiescent galaxy RUBIES-UDS-QG-z7 at z = 7.27. Observed with ALMA in band 6, the […

Hector Galaxy Survey: Optical IFU and Chandra Reveal a Low-Luminosity AGN Behind Extended LINER Emission

Kyuseok Oh, Gabriella Quattropani, Pratyush Kumar Das +25

We present evidence that the Hector Galaxy Survey galaxy C901005481609968 (), which exhibits spatially extended LINER-like emission in optical integral-field spe…

Transient Relativistic Iron Emission Line from an X-ray Flaring Supermassive Black Hole

Xiurui Zhao, Marco Ajello, Francesca Civano +16

We report the discovery of the first transient relativistic iron Kα line in an Active Galactic Nucleus (AGN) J1047+5907. The line was detected 21.5 days (rest-frame) after an X-ra…

The X-ray Emission of NGC 5005: An Unobscured Low-Luminosity AGN with a Weakly Accreting Broad-Line Region

Anna Trindade Falcão, R. Middei, G. Fabbiano +5

We present deep Chandra X-ray observations of NGC 5005, a LINER-dominated galaxy previously reported to host a broad H emission line. The diffuse soft X-ray emission (3 keV)…

Mapping the Excitation Mechanisms in the LINER I Active Galactic Nucleus NGC 5005: Positive Feedback and a Thin LINER Cocoon

Anna Trindade Falcão, G. Fabbiano, M. Elvis +5

We present a spatially resolved Baldwin-Phillips-Terlevich analysis of the narrow-line region (NLR) in the low-ionization nuclear emission-line region (LINER) I galaxy NGC 5005 usi…
