CHEX-MATE: A non-parametric deep learning technique to deproject and deconvolve galaxy cluster X-ray temperature profiles

A. Iqbal, G. W. Pratt, J. Bobin +21

Temperature profiles of the hot galaxy cluster intracluster medium (ICM) have a complex non-linear structure that traditional parametric modelling may fail to fully approximate. Fo…

Still alive and kicking: A significant outburst in changing-look AGN Mrk 1018

R. Brogan, M. Krumpe, D. Homan +13

Changing-look active galactic nuclei (CL-AGN) have been observed to change optical spectral type. Mrk 1018 is unique: first classified as a type 1.9 Seyfert galaxy, it transitioned…

CHEX-MATE: CLUster Multi-Probes in Three Dimensions (CLUMP-3D), I. Gas Analysis Method using X-ray and Sunyaev-Zel'dovich Effect Data

Junhan Kim, Jack Sayers, Mauro Sereno +23

Galaxy clusters are the products of structure formation through myriad physical processes that affect their growth and evolution throughout cosmic history. As a result, the matter…

X-ray Cavity Dynamics and their Role in the Gas Precipitation in Planck Sunyaev-Zeldovich (SZ) Selected Clusters

V. Olivares, Y. Su, W. Forman +7

We study active galactic nucleus (AGN) feedback in nearby (z<0.35) galaxy clusters from the Planck Sunyaev-Zeldovich (SZ) sample using Chandra observations. This nearly unbiased ma…

Compton-thick AGN in the NuSTAR Era X: Analysing seven local CT-AGN candidates

Dhrubojyoti Sengupta, Stefano Marchesi, Cristian Vignali +14

We present the broad-band X-ray spectral analysis (0.6-50 keV) of seven Compton-Thick active galactic nuclei (CT-AGN; line-of-sight, l.o.s., column density cm) ca…

Inferences from surface brightness fluctuations of Zwicky 3146 via the Sunyaev-Zeldovich effect and X-ray observations

Charles E. Romero, Massimo Gaspari, Gerrit Schellenberger +16

The galaxy cluster Zwicky 3146 is a sloshing cool core cluster at that in SZ imaging does not appear to exhibit significant pressure substructure in the intracluster me…

CHEX-MATE: Constraining the origin of the scatter in galaxy cluster radial X-ray surface brightness profiles

I. Bartalucci, S. Molendi, E. Rasia +25

We investigate the statistical properties and the origin of the scatter within the spatially resolved surface brightness profiles of the CHEX-MATE sample, formed by 118 galaxy clus…

Physical cool-core condensation radius in massive galaxy clusters

Lei Wang, Paolo Tozzi, Heng Yu +2

We investigate the properties of cool cores in an optimally selected sample of 37 massive and X-ray-bright galaxy clusters, with regular morphologies, observed with Chandra. We mea…

Dynamical complexity in micro-scale disk-wind systems

Fabrizio Fiore, Massimo Gaspari, Alfredo Luminari +2

Powerful winds at accretion-disk scales have been observed in the past 20 years in many AGN. These are the so-called ultrafast outflows (UFOs). Outflows are intimately related to m…

Unraveling Baroclinicity in Black Hole Weather Storms

Denis Wittor, Massimo Gaspari

In the intracluster, intragroup, and circumgalactic medium (ICM, IGrM, CGM), turbulence plays a vital role in the self-regulated feedback and feeding cycle of central supermassive…

The fraction and kinematics of broad absorption line quasars across cosmic time

Manuela Bischetti, Fabrizio Fiore, Chiara Feruglio +17

Luminous quasars are powerful targets to investigate the role of feedback from supermassive black-holes (BHs) in regulating the growth phases of BHs themselves and of their host ga…
