Thermal Sunyaev-Zel'dovich Effect in the circumgalactic medium - III: does richness matter?
Sanskriti Das, Yi-Kuan Chiang, Smita Mathur
We measure the thermal Sunyaev-Zel'dovich Effect in the circumgalactic/intragroup medium (CGM/IGrM) of 7 million M DESI Legacy Su…
Diffuse HI emission in the circumgalactic medium of NGC891 and NGC4565 - III: azimuthal profiles
Mary Rickel, Sanskriti Das, Nickolas M. Pingel +4
Diffuse HI emission in the circumgalactic medium (CGM) of NGC891 and NGC4565 has been previously shown to trace an inflow along minor axes pointings and to co-rotate with the HI di…
Thermal Structure and Chemical Enrichment of the North and South Polar Spurs: Supersolar N/O and Ne/O in the X-ray Plasma
Anjali Gupta, Smita Mathur, Joshua Kingsbury +5
The North Polar Spur (NPS) is a prominent diffuse X-ray feature whose origin has remained uncertain for decades. Using a uniform analysis of archival \textit{Suzaku} and \textit{XM…
The Nuclear Star Cluster of M 74: a fossil record of the very early stages of a star-forming galaxy
Francesca Pinna, Nils Hoyer, Jairo Méndez Abreu +13
Nuclear star clusters (NSC) are dense and compact stellar systems, of sizes of few parsecs, located at galactic centers. Their properties and formation mechanisms seem to be tightl…
Deep X-ray observation of NGC 3221: everything everywhere all at once
Sanskriti Das, Smita Mathur, Bret D. Lehmer +3
We present a comprehensive analysis of 475 ks (438 ks unpublished & 37 ks archival) XMM-Newton/EPIC-pn observation of a nearby, highly inclined, star-forming, luminous infrared gal…
Resolved HII regions in NGC 253: Ionized gas structure and suggestions of a universal density-surface brightness relation
Rebecca L. McClain, Adam K. Leroy, Enrico Congiu +23
We use the full-disk VLT-MUSE mosaic of NGC 253 to identify 2492 HII regions and study their resolved structure. With an average physical resolution of 17 pc, this is one of the la…
Detection of 'super-virial' gas in the Circumgalactic medium of the Milky Way towards PKS 2155-304
Mukesh Singh Bisht, Sanskriti Das, Smita Mathur +3
We present the first simultaneous detection of four distinct highly ionized absorbing phases using Chandra and XMM-Newton grating spectra toward the blazar PKS 2155…
Thermal Sunyaev-Zel'dovich Effect in the circumgalactic medium -- II: dependence on star formation
Sanskriti Das, Nhut Truong, Yi-Kuan Chiang +1
We measure thermal Sunyaev-Zel'dovich (tSZ) Effect in the circumgalactic medium (CGM) of 2.5 million = WISEDESI galaxies out…
Where is the Supervirial Gas? III. Insights from X-ray Shadow Observations and a revised Model for the Soft Diffuse X-ray Background
Anjali Gupta, Smita Mathur, Joshua Kingsbury +5
Shadow observations provide a powerful tool to separate foreground components of the soft diffuse X-ray background (SDXB) from the background components. Such observations have now…
Where is the Super-virial Gas? II: Insight from the Survey of Galactic Sightlines
Manami Roy, Smita Mathur, Sanskriti Das +3
Recent observations have revealed a super-virial temperature gas phase at log(T/K) in the Milky Way, challenging existing galaxy-formation models. This hot gas phase was di…
On the origin of the K hot emitting gas in the Circumgalactic medium of the Milky Way
Mukesh Singh Bisht, Biman B. Nath, Smita Mathur
The presence of the K gas in the circumgalactic medium of the Milky Way has been well established. However, the location and the origin of the newly discovered hot g…
Where is the Super-Virial Gas? The Supply from hot inflows
Manami Roy, Kung-Yi Su, Smita Mathur +1
In an effort to understand the presence of super-virial gas detected in the Milky Way, we present our findings from isolated galaxy simulations of Milky Way-like systems using GIZM…
The LeMMINGs survey: probing sub-kpc radio structures of nearby galaxies with e-MERLIN
David R. A. Williams, Ranieri D. Baldi, Robert J. Beswick +10
The Legacy e-MERLIN Multi-band Imaging of Nearby Galaxies survey (LeMMINGs) is a statistically-complete census of nuclear accretion and star formation processes in the local Univer…
Hubble Space Telescope Observations of BALQSO Ton 34 Reveal a Connection between the Broad Line Region and the BAL Outflow
Y. Krongold, L. Binette, R. Bohlin +7
Ton 34 recently transitioned from non-absorbing quasar into a BALQSO.Here, we report new HST-STIS observations of this quasar. Along with CIV absorption, we also detect absorption…
Exploring the parent population of beamed NLS1s: from the black hole to the jet
M. Berton, L. Foschini, S. Ciroi +11
The aim of this work is to understand the nature of the parent population of beamed narrow-line Seyfert 1 galaxies (NLS1s), by studying the physical properties of three parent cand…
Basic properties of Narrow-Line Seyfert 1 Galaxies with Relativistic Jets
L. Foschini, E. Angelakis, G. Bonnoli +25
We present the preliminary results of a survey performed with Swift to observe a sample of radio-loud Narrow-Line Seyfert 1 Galaxies (RLNLS1s). Optical-to-X-ray data from Swift are…
