Cool dark sector, concordance, and a low
Ellie Hughes, Fei Ge, Francis-Yan Cyr-Racine +2
We investigate a cosmological model in which a fraction of the dark matter is atomic dark matter (ADM). This ADM consists of dark versions of the electron and of the proton, intera…
Arithmetic progressions of integers that are relatively prime to their digital sums
Ryan Blau, Joshua Harrington, Sarah Lohrey +2
For an integer , we call a positive integer -anti-Niven if it is relatively prime to the sum of the digits in its base- representation. In this article, we investiga…
A Candidate Dual QSO at Cosmic Noon
Eilat Glikman, Rachel Langgin, Makoto A. Johnstone +6
We report the discovery of a candidate dual QSO at z=1.889, a redshift that is in the era known as "cosmic noon" where most of the Universe's black hole and stellar mass growth occ…
Interfacial and Surface Magnetism in Epitaxial NiCo2O4(001)/MgAl2O4 Films
Corbyn Mellinger, Xiao Wang, Arjun Subedi +6
NiCo2O4 (NCO) films grown on MgAl2O4 (001) substrates have been studied using magnetometry, x-ray magnetic circular dichroism (XMCD) based on x-ray absorption spectroscopy, and spi…
