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…
The host galaxy of GRB 980425 / SN1998bw: a collisional ring galaxy
M. Arabsalmani, S. Roychowdhury, T. K. Starkenburg +8
We report Giant Metrewave Radio Telescope (GMRT) , Very Large Telescope (VLT) and Spitzer Space Telescope observations of ESO 184G82, the host galaxy of GRB 980425/SN 1998bw, th…
HI 21cm mapping of the host galaxy of AT2018cow: a fast-evolving luminous transient within a ring of high column density gas
Sambit Roychowdhury, Maryam Arabsalmani, Nissim Kanekar
We report Giant Metrewave Radio Telescope (GMRT) HI 21cm imaging of CGCG 137-068, the host galaxy of the fast-evolving luminous transient (FELT) AT2018cow. This is the first study…
A systematic metallicity study of DustPedia galaxies reveals evolution in the dust-to-metal ratios
P. De Vis, A. Jones, S. Viaene +17
Observations of evolution in the dust-to-metal ratio allow us to constrain the dominant dust processing mechanisms. In this work, we present a study of the dust-to-metal and dust-t…
