Peculiar velocities at low Galactic latitude
Jeremy Mould, Helene M. Courtois, Renee C. Kraan-Korteweg +1
The Laniakea Supercluster is the closest large scale structure of galaxies. Is such a structure expected in the standard cold dark matter model of cosmology? This would be a relati…
AMPM II. A Lunar-Mass Primordial Black Hole Microlensing Candidate in the Milky Way Halo
Renee Key, Edward N. Taylor, Ken C. Freeman +5
Primordial Black Holes (PBH) are hypothesised to form during inflation and have long been considered a candidate for compact dark matter. Gravitational microlensing is known as a p…
AMPM I. A Targeted Search for Asteroid Mass Primordial Black Hole Microlenses
Renee Key, Edward N. Taylor, Ken C. Freeman +5
Gravitational microlensing is a powerful technique for constraining the abundance of dark matter in asteroid mass to supermassive primordial black holes at masses of $-11 \lesssim…
The Dark Energy Survey: Cosmology Results With ~1500 New High-redshift Type Ia Supernovae Using The Full 5-year Dataset
DES Collaboration, T. M. C. Abbott, M. Acevedo +156
We present cosmological constraints from the sample of Type Ia supernovae (SN Ia) discovered during the full five years of the Dark Energy Survey (DES) Supernova Program. In contra…
Calibrating the Absolute Magnitude of Type Ia Supernovae in Nearby Galaxies using [OII] and Implications for
M. Dixon, J. Mould, C. Lidman +69
The present state of cosmology is facing a crisis where there is a fundamental disagreement in measurements of the Hubble constant (), with significant tension between the e…
