PublicationCOLDz: A High Space Density of Massive Dusty Starburst Galaxies ∼1 Billion Years after the Big Bang
We report the detection of CO(J = 2 → 1) emission from three massive dusty starburst galaxies at z > 5 through molecular line scans in the NSF's Karl G. Jansky...

TalkCompact Galaxies and Super Massive Black Holes
Most massive galaxies have supermassive black holes at their centres, and the masses of the black holes correlate with properties of the host-galaxy bulge...

TalkDark matter in early-type galaxies: a SAURON view
From galaxy formation theory we expect galaxies to be embedded in massive dark matter haloes. For spiral and dwarf galaxies this has indeed been observationally...

TalkDark matter in galaxies
The distribution of matter in galaxies of different luminosities and Hubble types, as inferred from observations, plays an important role in cosmology...

PublicationDESI Observations of the Andromeda Galaxy: Revealing the Immigration History of Our Nearest Neighbor
We present Dark Energy Spectroscopic Instrument (DESI) observations of the inner halo of M31, which reveal the kinematics of a recent merger-a galactic...

PublicationDiscovery of Four Apparently Cold Dusty Galaxies at z = 3.62─5.85 in the COSMOS Field: Direct Evidence of Cosmic Microwave Background Impact on High-redshift Galaxy Observables
We report Atacama Large Millimeter Array (ALMA) observations of four high-redshift dusty star-forming galaxy candidates selected from far-infrared (FIR)...

TalkDoes it take a supercluster to raise a galaxy?
Galaxies in different environments have different properties. In dense environments galaxies are more likely to be red, passive ellipticals than in less dense...

TalkDynamics of galaxies and globular clusters unraveled with two-dimensional kinematics
Two-dimensional stellar kinematics obtained with the integral-field spectrograph SAURON allow the classification of early-type galaxies into 'slow' and 'fast'...
