Do stars still form in molecular gas within CO-dark dwarf galaxies?

Robin Gopala Tress

In the Milky Way and other main-sequence galaxies, stars form exclusively in molecular gas, which is traced by CO emission. However, low-metallicity dwarf galaxies are often 'CO-dark' in the sense that CO emission is not observable even at the high resolut ...

Tip of the Red Giant Branch Distances with JWST: An Absolute Calibration in NGC 4258 and First Applications to Type Ia Supernova Hosts

Richard Irving Anderson

The tip of the red giant branch (TRGB) allows for the measurement of precise and accurate distances to nearby galaxies based on the brightest ascent of low-mass red giant branch stars before they undergo the helium flash. With the advent of JWST, there is ...

Kinematics of Galactic Centre clouds shaped by shear-seeded solenoidal turbulence

Robin Gopala Tress

The Central Molecular Zone (CMZ; the central & SIM;500 pc of the Galaxy) is a kinematically unusual environment relative to the Galactic disc, with high-velocity dispersions and a steep size-linewidth relation of the molecular clouds. In addition, the CMZ ...

Star formation histories, extinction, and dust properties of strongly lensed z similar to 1.5-3 star-forming galaxies from the Herschel Lensing Survey

Jean-Paul Richard Kneib

Context. Multi-wavelength, optical to IR/submm observations of strongly lensed galaxies identified by the Herschel Lensing Survey are used to determine the physical properties of high-redshift star-forming galaxies close to or below the detection limits of ...
