DOI: 10.1017/pasa.2025.9
Abstract: The initial mass function (IMF) is a construct that describes the distribution of stellar masses for a newly formed population of stars. It is a fundamental element underlying all of star and galaxy formation, and… read more here.

DOI: 10.1017/s0003055417000430
Abstract: Whether public policy affects electoral politics is an enduring question with an elusive answer. We identify the impact of the highly contested Patient Protection and Affordable Care Act (ACA) of 2010 by exploiting cross-state variation… read more here.

DOI: 10.1093/mnras/staa1926
Abstract: Magnetic fields play an important role for the formation of stars in both local and high-redshift galaxies. Recent studies of dynamo amplification in the first dark matter haloes suggest that significant magnetic fields were likely… read more here.

DOI: 10.1093/mnras/staf059
Abstract: We report the stellar mass functions obtained from 20 radiation hydrodynamical simulations of star cluster formation in 500 M⊙ molecular clouds with metallicities of 3, 1, 1/10 and 1/100 of the solar value, with the clouds… read more here.

DOI: 10.1093/mnras/stx2734
Abstract: There are a growing number of nearby SNe for which the progenitor star is detected in archival pre-explosion imaging. From these images it is possible to measure the progenitor's brightness a few years before explosion,… read more here.

DOI: 10.1093/mnras/stz1398
Abstract: We present predictions for the UV-to-mm extragalactic background light (EBL) from a recent version of the GALFORM semi-analytical model of galaxy formation which invokes a top-heavy stellar initial mass function (IMF) for galaxies undergoing dynamically… read more here.

DOI: 10.3390/universe10030141
Abstract: We aim to constrain the stellar initial mass function (IMF) during the epoch of reionization. To this purpose, we build up a semi-empirical model for the reionization history of the Universe based on various ingredients:… read more here.
