Coarse cohomology of the complement
Arka Banerjee, Boris Okun
In this paper we define the coarse (co)homology of the complement of a subspace in a metric space, generalizing the coarse (co)homology of Roe. We give a model space which encodes…
Non-thermal warm dark matter limits from small-scale structure
Arka Banerjee, Subinoy Das, Anshuman Maharana +2
We present small-scale structure constraints on sterile dark matter produced from a heavy mediator particle, inspired by models of moduli decay. Dark matter particles produced thro…
The Merian Survey: Design, Construction, and Characterization of a Filter Set Optimized to Find Dwarf Galaxies and Measure their Dark Matter Halo Properties with Weak Lensing
Yifei Luo, Alexie Leauthaud, Jenny Greene +28
The Merian survey is mapping 850 degrees of the Hyper Suprime-Cam Strategic Survey Program (HSC-SSP) wide layer with two medium-band filters on the 4-meter Victor M. Bla…
Aemulus : Precise Predictions for Matter and Biased Tracer Power Spectra in the Presence of Neutrinos
Joseph DeRose, Nickolas Kokron, Arka Banerjee +6
We present the Aemulus simulations: a suite of 150 -body simulations with a mass resolution of $3.51\times 10^{10} \frac{Ω_{cb}}{0.3} ~ h^{-1} M_{\o…
