H I Properties of Field Galaxies at -0.6: Insights into Declining Cosmic Star Formation
David DePalma, Neeraj Gupta, Hsiao-Wen Chen +18
We report statistically significant detection of H I 21-cm emission from intermediate-redshift (-0.6) galaxies. By leveraging multi-sightline galaxy survey data from t…
The Close AGN Reference Survey (CARS): A comparison between sub-mm and optical AGN diagnostic diagrams
Jacob S. Elford, Timothy A. Davis, Ilaria Ruffa +9
The relation suggests that there is a tight connection between dense gas and star formation. We use data from the Close AGN Reference Survey (CARS) to inve…
The Close AGN Reference Survey (CARS). Long-term spectral variability study of the changing look AGN Mrk 1018
T. Saha, M. Krumpe, A. Markowitz +9
Changing-look AGNs (CLAGN) are accreting supermassive black hole systems that undergo variations in optical spectral type, driven by major changes in accretion rate. Mrk 1018 has u…
Evidence for a sub-jovian planet in the young TWA7 disk
A. -M. Lagrange, C. Wilkinson, M. Mâlin +26
Planets are thought to form from dust and gas in protoplanetary disks, and debris disks are the remnants of planet formation. Aged a few Myr up to a few Gyr, debris disks have lost…
A case study of gas impacted by black-hole jets with the JWST: outflows, bow shocks, and high excitation of the gas in the galaxy IC5063
K. M. Dasyra, G. F. Paraschos, F. Combes +8
We present James Webb Space Telescope MIRI data of the inner 3x2kpc^2 of the galaxy IC5063, in which the jets of a supermassive black hole interact with the gaseous disk they are c…
SN 1885A and supernova remnants in the centre of M31 with LOFAR
Deepika Venkattu, Peter Lundqvist, Miguel Pérez Torres +4
We present the first LOFAR image of the centre of M31 at a frequency of 150 MHz. We clearly detect three supernova remnants, which, along with archival VLA data at 3 GHz and other…
