The formation histories of massive and quiescent galaxies in the 3 < z < 4.5 Universe

Themiya Nanayakkara, Karl Glazebrook, Corentin Schreiber +16

We present the formation histories of 19 massive () quiescent (sSFR) galaxy candidates at z~3.0-4.5 observed using JWST/NIRSpec. This completes th…

The FENIKS Survey: Multi-wavelength Photometric Catalog in the UDS Field, and Catalogs of Photometric Redshifts and Stellar Population Properties

Kumail Zaidi, Danilo Marchesini, Casey Papovich +11

We present the construction of a deep multi-wavelength PSF-matched photometric catalog in the UDS field following the final UKIDSS UDS DR11 release. The catalog includes photometry…

A massive galaxy that formed its stars at

Karl Glazebrook, Themiya Nanayakkara, Corentin Schreiber +15

The formation of galaxies by gradual hierarchical co-assembly of baryons and cold dark matter halos is a fundamental paradigm underpinning modern astrophysics and predicts a strong…

The FENIKS Survey: Spectroscopic Confirmation of Massive Quiescent Galaxies at z ~ 3-5

Jacqueline Antwi-Danso, Casey Papovich, James Esdaile +13

The measured ages of massive, quiescent galaxies at imply that massive galaxies quench as early as . While the number of spectroscopic confirmations of quiesce…

A population of faint, old, and massive quiescent galaxies at 3 < z < 4 revealed by JWST NIRSpec Spectroscopy

Themiya Nanayakkara, Karl Glazebrook, Colin Jacobs +13

Here we present a sample of 12 massive quiescent galaxy candidates at z~3-4 observed with the James Webb Space Telescope (JWST) Near Infrared Spectrograph (NIRSpec). These galaxies…

Introducing the FLAMINGOS-2 Split-K Medium Band Filters: The Impact on Photometric Selection of High-z Galaxies in the FENIKS-pilot survey

James Esdaile, Ivo Labbe, Karl Glazebrook +11

Deep near-infrared photometric surveys are efficient in identifying high-redshift galaxies, however they can be prone to systematic errors in photometric redshift. This is particul…

Massive High-Redshift Quiescent Galaxies With JWST

Themiya Nanayakkara, James Esdaile, Karl Glazebrook +3

Recent ground-based deep observations of the Universe have discovered large populations of massive quiescent galaxies at z~3-5. With the launch of the James Webb Space Telescope (J…

Consistent dynamical and stellar masses with potential light IMF in massive quiescent galaxies at using velocity dispersions measurements with MOSFIRE

James Esdaile, Karl Glazebrook, Ivo Labbe +9

We present the velocity dispersion measurements of four massive quiescent galaxies at based on deep H and Kband spectra using the Keck/MOSFI…

Fundamental relations for the velocity dispersion of stars in the Milky Way

Sanjib Sharma, Michael R. Hayden, Joss Bland-Hawthorn +34

We explore the fundamental relations governing the radial and vertical velocity dispersions of stars in the Milky Way, from combined studies of complementary surveys including GALA…

The K2-HERMES Survey: Age and Metallicity of the Thick Disc

Sanjib Sharma, Dennis Stello, Joss Bland-Hawthorn +34

Asteroseismology is a promising tool to study Galactic structure and evolution because it can probe the ages of stars. Earlier attempts comparing seismic data from the {\it Kepler}…

The K2-HERMES Survey. I. Planet Candidate Properties from K2 Campaigns 1-3

Robert A. Wittenmyer, Sanjib Sharma, Dennis Stello +31

Accurate and precise radius estimates of transiting exoplanets are critical for understanding their compositions and formation mechanisms. To know the planet, we must know the host…
