Formation of multiphase plasma in galactic haloes and an analogy to solar plasma

Frontiers in Astronomy and Space Sciences, 2023
Thermal instability (TI) potentially explains the origin of cold gas in the intracluster medium (ICM), which is heated sufficiently by AGN feedback. The Hα filaments seen in cluster cores provide strong motivation for TI.

Measuring bulk flows of the intracluster medium in the Perseus and Coma galaxy clusters using XMM-Newton [PDF]

Astronomy & Astrophysics, 2019
We demonstrate a novel technique for calibrating the energy scale of the EPIC-pn detector on XMM-Newton, which allows us to measure bulk flows in the intracluster medium (ICM) of the Perseus and Coma galaxy clusters.

Mapping the intracluster medium temperature in the era of NIKA2 and MUSTANG-2 [PDF]

EPJ Web of Conferences, 2022
We present preliminary results from an on-going program that aims at mapping the intracluster medium (ICM) temperature of high redshift galaxy clusters from the MaDCoWS sample using a joint analysis of shallow X-ray data obtained by Chandra and high ...

NGC 7421: Surfing the Intracluster Medium? [PDF]

Publications of the Astronomical Society of Australia, 1997
AbstractNGC 7421 is a barred spiral that is displaced from the centre of its optical envelope, and has a ‘bow-shock’-like western boundary, both suggestive of interaction with an intracluster medium. We have used five configurations of the ATCA to map the distribution and kinematics of HI in NGC 7421, and find supportive evidence for this scenario in ...

The loss of the intracluster medium in globular clusters [PDF]

, 2020
Stars in globular clusters (GCs) lose a non negligible amount of mass during their post-main sequence evolution. This material is then expected to build up a substantial intra-cluster medium (ICM) within the GC.

Broad Band Optical Polarimetric Study of IC 1805 [PDF]

, 2007
We present the BVR broad band polarimetric observations of 51 stars belonging to the young open cluster IC 1805. Along with the photometric data from the literature we have modeled and subtracted the foreground dust contribution from the maximum ...

Power spectrum estimation methods on intracluster medium surface brightness fluctuations [PDF]

EPJ Web of Conferences
Accurate estimation of galaxy cluster masses is a central problem in cosmology. Turbulence is believed to introduce significant deviations from the hydrostatic mass estimates.

Novel Sulfonium Reagents for the Modular Synthesis of Spiro[2.3]Hexanes and Heteroatom‐Containing Analogues: Synthesis, Application, and Evaluation as Bioisosteres

Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.
Strained spirocyclic spiro[2.3]hexane and its heteroatom‐containing derivatives, including previously underrepresented 5‐oxa‐1‐azaspiro[2.3]hexanes and 1,5‐diazaspiro[2.3]hexanes, were synthesized via a modular approach of insertion of cyclobutane‐, oxetane‐, and azetidine‐containing sulfonium reagents into alkenes, carbonyls and imines.

Understanding shape and centroid deviations in 39 strong lensing galaxy clusters in various dynamical states [PDF]

EPJ Web of Conferences
Through observational tests of strong lensing galaxy clusters, we can test simulation derived structure predictions that follow from Λ Cold Dark Matter (ΛCDM) cosmology.
