Diverse reddening distributions in sight lines to type Ia supernovae

Lucas Hallgren, Radoslaw Wojtak, Jens Hjorth +1

Precise cosmological constraints from type Ia supernovae require adequately accurate corrections for host-galaxy extinction. Modelling these corrections is challenged by the proble…

Dark Energy Constraints and Joint Cosmological Inference from Mutually Inconsistent Observations

Charles L. Steinhardt, Preston Phillips, Radoslaw Wojtak

Recent results regarding dark energy are mutually inconsistent under the CDM cosmological model, hinting at the possibility of undiscovered physics. However, the currently accep…

Optimal parameterizations for observational constraints on thawing dark energy

David Shlivko, Paul J. Steinhardt, Charles L. Steinhardt

Time-varying dark energy is often modeled in observational analyses through generic parameterizations of its equation of state , which typically use two free parameters $\{w_…

A power spectral study of PHANGS galaxies with JWST MIRI: On the spatial scales of dust and PAHs

Charlie Lind-Thomsen, Albert Sneppen, Charles L. Steinhardt

The interstellar medium (ISM) consists of a diversity of structures across a range of spatial scales, intimately tied to galactic evolution. In this work, Fourier analysis is used…

Evidence for Multiple Types of Post-Starburst Galaxies

Emma W. Nielsen, Charles L. Steinhardt, Mathieux Harper +2

The quenching mechanisms of galaxies are not yet fully understood, but post-starburst galaxies provide one explanation for the rapid transition between star-forming and quiescent g…

No [CII] or dust detection in two Little Red Dots at z > 7

Mengyuan Xiao, Pascal A. Oesch, Longji Bing +30

Little Red Dots (LRDs) are compact, point-like sources characterized by their red color and broad Balmer lines, which have been debated to be either dominated by active galactic nu…
