ALMA-JELLY II. Constraining the radial profiles of the quenching timescales in ram-pressure-stripped galaxies
Roberto P. Infurna, Matteo Fossati, Alessandro Boselli +21
We investigate the environmental quenching histories and spatial progression of ram-pressure stripping in 11 galaxies in the nearby Coma, Norma, and A1367 clusters. As part of the…
CHANG-ES XL: Magnetic Field Structures in the Disk and Halo of NGC 891
N. Pourjafari, J. M. Stil, R. -J. Dettmar +11
We present new Karl G. Jansky Very Large Array S-band (2-4 GHz) observations of the edge-on spiral galaxy NGC 891, complemented by C-band data, to investigate the structure of its…
AstroSat UVIT Survey of M31: New Compact Source Catalog
Denis Leahy, Sujith Ranasinghe, Saptadwipa Mitra +1
An ultraviolet survey of M31 has been carried out during 2017-23 with the UVIT instrument onboard the AstroSat Observatory. Here we present far and near ultraviolet (FUV and NUV) o…
A Statistical Analysis of Galactic Radio Supernova Remnants
S. Ranasinghe, D. Leahy
We present an revised table of 390 Galactic radio supernova remnants (SNRs) and their basic parameters. Statistical analyses are performed on SNR diameters, ages, spectral indices,…
Discovery of 20 UV Emitting SNRs in M31 with UVIT
Denis Leahy, Christopher Monaghan, Sujith Ranasinghe
We present the first catalog of supernova remnants (SNRs) in M31 which exhibit diffuse ultraviolet (UV) emission. UV images of M31 were obtained by the Ultraviolet Imaging Telescop…
Search for and Identification of Young Compact Galactic Supernova Remnants Using THOR
S. Ranasinghe, D. Leahy, J Stil
Young Supernova remnants (SNRs) with smaller angular sizes are likely missing from existing radio SNR catalogues, caused by observational constraints and selection effects. In orde…
Emission Measures and Emission-measure-weighted Temperatures of Shocked ISM and Ejecta in Supernova Remnants
D. A. Leahy, Yuyang Wang, Bryson Lawton +2
A goal of supernova remnant (SNR) evolution models is to relate fundamental parameters of a supernova (SN) explosion and progenitor star to the current state of its SNR. The SNR ho…
Evolutionary Models for 15 Galactic Supernova Remnants with New Distances
D. A. Leahy, S. Ranasinghe
Recent studies using 21 cm HI line and CO line observations in the inner part of the Galaxy have resulted in new distances for 30 Galactic supernova remnants (SNRs). 15 of t…
Revised Distances to 21 Supernova Remnants
S. Ranasinghe, D. A. Leahy
We carry out a comprehensive study of HI 21 cm line observations and CO line observations of 21 supernova remnants (SNRs). The aim of the study is to search for HI absorptio…
New Distances to Four Supernova Remnants
S. Ranasinghe, D. A. Leahy, Wenwu Tian
Distances are found for four supernova remnants without previous distance measurements. H I spectra and H I channel maps are used to determine the maximum velocity of H I absorptio…
Distances to Supernova Remnants G, G and G and New Molecular Cloud Associations
S. Ranasinghe, D. A. Leahy
Accurate distances to supernova remnants (SNRs) are crucial in determining their size, age, luminosity and evolutionary state. To determine distances, we chose three SNRs from the…
HI absorption spectra for Supernova Remnants in the VGPS survey
Denis Leahy, Sujith Ranasinghe
The set of supernova remnants (SNR) from Green's SNR catalog which are found in the VLA Galactic Plane Survey (VGPS) are the objects considered in this study. For these SNR, we ext…
X-ray and Radio Observations of the gamma Cygni Supernova Remnant G78.2+2.1
D. A. Leahy, K. Green, S. Ranasinghe
We analyse \textit{ROSAT} and \textit{Chandra} ACIS X-ray observations and HI absorption spectra of the Cygni supernova remnant (G78.2+2.1, DR4). The \textit{ROSAT} All-Sky-Sur…
