The Rise of Ionized Gas Filaments in Early-Type Galaxies

Ryan Eskenasy, Valeria Olivares, Yuanyuan Su

Multiphase filamentary nebulae are ubiquitous in the brightest cluster galaxies (BCGs) of cool-core clusters, providing insight into baryon cycling and the feeding and feedback of…

AMUSE-Antlia. II. Intracluster X-ray Population in the Antlia Cluster

Zhensong Hu, Yuanyuan Su, Zhiyuan Li +4

We conduct a systematic survey of X-ray sources in the inner ( kpc) region of the Antlia cluster based on \Chandra observations, down to a source detection limit of $ L(0…

Constraints on Non-Thermal Pressure at galaxy cluster outskirts from a Joint SPT and XMM-Newton Analysis

Arnab Sarkar, Michael McDonald, Lindsey Bleem +11

We present joint South Pole Telescope (SPT) and XMM-Newton observations of 8 massive galaxy clusters (0.8--1.710 M) spanning a redshift range of 0.16 to 0.…

Semi-supervised Learning for Detecting Inverse Compton Emission in Galaxy Clusters

Sheng-Chieh Lin, Yuanyuan Su, Fabio Gastaldello +1

Inverse Compton (IC) emission associated with the non-thermal component of the intracluster medium (ICM) has been a long sought phenomenon in cluster physics. Traditional spectral…

On the Particle Acceleration Mechanisms in a Double Radio Relic Galaxy Cluster, Abell 1240

Arnab Sarkar, Felipe Andrade-Santos, Reinout J. van Weeren +12

We present a 368 ks deep Chandra observation of Abell~1240, a binary merging galaxy cluster at a redshift of 0.195 with two Brightest Cluster Galaxies (BCGs) may have passed each o…

X-Ray Constraints on the Hot Gaseous Corona of Edge-on Late-type Galaxies in Virgo

Meicun Hou, Lin He, Zhensong Hu +6

We present a systematic study of the putative hot gas corona around late-type galaxies (LTGs) residing in the Virgo cluster, based on archival Chandra observations. Our sample cons…

The formation channels of multiphase gas in nearby early-type galaxies

Ryan Eskenasy, Valeria Olivares, Yuanyuan Su +1

The processes responsible for the assembly of cold and warm gas in early-type galaxies (ETGs) are not well-understood. We report on the multiwavelength properties of 15 non-central…

The composition and thermal properties of a cool core lacking a brightest cluster galaxy

Yuanyuan Su, Francoise Combes, Valeria Olivares +3

We present a multiwavelength observation of a cool core that does not appear to be associated with any galaxy, in a nearby cluster, Abell~1142. Its X-ray surface brightness peak of…

Exploring chemical enrichment of the intracluster medium with the Line Emission Mapper

François Mernier, Yuanyuan Su, Maxim Markevitch +27

Synthesized in the cores of stars and supernovae, most metals disperse over cosmic scales and are ultimately deposited well outside the gravitational potential of their host galaxi…

Mapping the Intracluster Medium in the Era of High-resolution X-ray Spectroscopy

Congyao Zhang, Irina Zhuravleva, Maxim Markevitch +24

High-resolution spectroscopy in soft X-rays will open a new window to map multiphase gas in galaxy clusters and probe physics of the intracluster medium (ICM), including chemical e…
