CDM in a courtroom
Ofer Lahav, Paul Shah
The cosmological constant , and its generalization as Dark Energy, makes up roughly 70% of the present-epoch universe and has been part of the dominant CDM cosmological parad…
Supernovae Unite: Combining Pantheon+ and DES-SN5YR
Ryan Camilleri, Jaemyoung Lee, Tamara Davis +21
We present the Hubble diagram and cosmological constraints resulting from the combination of the Pantheon+ and DES-SN5YR supernova (SN) samples, which we refer to as Unite. Unite u…
Probing Physics Beyond the Standard Model through Combined Analyses of Next-Generation Type Ia Supernova, CMB, and BAO Surveys
Srinivasan Raghunathan, Ayan Mitra, Nikolina Šarčević +11
Observations of Type Ia supernovae (\sne), which probe the late Universe, together with baryon acoustic oscillations (BAO) and the cosmic microwave background (CMB), which probe th…
The Cosmic Microwave Background and
Pablo Lemos, Paul Shah
The cosmic microwave background (CMB) offers a unique window into the early universe, providing insights into cosmological parameters like the Hubble constant. Recent precise measu…
The impact of weak lensing on Type Ia supernovae luminosity distances
Paul Shah, Pablo Lemos, Ofer Lahav
When Type Ia supernovae are used to infer cosmological parameters, their luminosities are compared to those from a homogeneous cosmology. In this note we propose a test to examine…
Weak lensing magnification of Type Ia Supernovae from the Pantheon sample
Paul Shah, Pablo Lemos, Ofer Lahav
Using data from the Pantheon SN Ia compilation and the Sloan Digital Sky Survey (SDSS), we propose an estimator for weak lensing convergence incorporating positional and photometri…
A buyer's guide to the Hubble Constant
Paul Shah, Pablo Lemos, Ofer Lahav
Since the expansion of the universe was first established by Edwin Hubble and Georges Lemaitre about a century ago, the Hubble constant H0 which measures its rate has been of great…
