Molecular clouds in M51 from high-resolution extinction mapping
Helena Faustino Vieira, Ana Duarte-Cabral, Timothy A. Davis +5
Here we present the cloud population extracted from M51, following the application of our new high-resolution dust extinction technique to the galaxy (Faustino Vieira et al. 2023).…
A high-resolution extinction mapping technique for face-on disc galaxies
Helena Faustino Vieira, Ana Duarte-Cabral, Timothy A. Davis +5
We present a new dust extinction technique with which we are able to retrieve parsec-scale gas surface density maps for entire nearby galaxies. The method measures the dust attenua…
NGC 1436: the making of a lenticular galaxy in the Fornax cluster
Alessandro Loni, Paolo Serra, Marc Sarzi +25
We study the evolutionary path of the Fornax cluster galaxy NGC1436, which is known to be currently transitioning from a spiral into a lenticular morphology. This galaxy hosts a…
Metal Factories in the Early Universe
Stephen Eales, Haley Gomez, Loretta Dunne +2
We have measured the mass of metals in the molecular gas in 13 submillimetre galaxies at z~4 in which the gas, based on previous observations, lies in a cold rotating disk. We meas…
The Quest for the Missing Dust: II -- Two Orders of Magnitude of Evolution in the Dust-to-Gas Ratio Resolved Within Local Group Galaxies
Christopher J. R. Clark, Julia C. Roman-Duval, Karl D. Gordon +3
We explore evolution in the dust-to-gas ratio with density within four well-resolved Local Group galaxies - the LMC, SMC, M31, and M33. We do this using new maps,…
