The variation of the gas content of galaxy groups and pairs compared to isolated galaxies
Sambit Roychowdhury, Martin J. Meyer, Jonghwan Rhee +17
We measure how the atomic gas (HI) fraction () of groups and pairs taken as single units vary with average stellar mass ($\langle {\rm M_*} \rang…
WALLABY pre-pilot survey: Two dark clouds in the vicinity of NGC 1395
O. Ivy Wong, A. R. H. Stevens, B. -Q. For +34
We present the Australian Square Kilometre Array Pathfinder (ASKAP) WALLABY pre-pilot observations of two `dark' HI sources (with HI masses of a few times 10^8 Msol and no known st…
A Nearby Galaxy Perspective on Dust Evolution. Scaling relations and constraints on the dust build-up in galaxies with the DustPedia and DGS samples
Frédéric Galliano, Angelos Nersesian, Simone Bianchi +14
Methods. We have modelled a sample of ~800 nearby galaxies, spanning a wide range of metallicity, gas fraction, specific star formation rate and Hubble stage. We have derived the d…
Local starburst conditions and formation of GRB 980425 / SN 1998bw within a collisional ring
M. Arabsalmani, F. Renaud, S. Roychowdhury +9
We present the first spatially resolved study of molecular gas in the vicinity of a Gamma Ray Burst, using CO(2-1) emission line observations with the Atacama Large Millimetre Arra…
A first quantification of the effects of absorption for HI Intensity Mapping experiments
Sambit Roychowdhury, Clive Dickinson, Ian W. A. Browne
HI Intensity Mapping (IM) will be used to do precision cosmology using many existing and upcoming radio observatories. The signal will be contaminated due to absorption, the larges…
A superluminous supernova in high surface density molecular gas within the bar of a metal-rich galaxy
M. Arabsalmani, S. Roychowdhury, F. Renaud +8
We report the Atacama Large Millimeter/submillimeter Array (ALMA) observations of the metal rich host galaxy of superluminous supernova (SLSN) PTF10tpz, a barred spiral galaxy at z…
