What would it take for dark matter to be literally warm?
Katelin Schutz
Warm dark matter (WDM) has served as a valuable benchmark for constraining small-scale structure in the past decades. In this note, I examine what it would take for dark matter to…
Searching for axion dark matter gegenschein of the Vela supernova remnant with FAST
Wenxiu Yang, Yitian Sun, Yougang Wang +7
Axions are one of the leading dark matter candidates. If we are embedded in a Milky Way dark matter halo comprised of axions, their stimulated decay would enable us to observe a co…
An Effective Bias Expansion for 21 cm Cosmology in Redshift Space
Wenzer Qin, Katelin Schutz, Aaron Smith +4
A near-future detection of the 21cm signal from the epoch of reionization will provide unique opportunities to probe the underlying cosmology, provided that such cosmological infor…
The cosmology of sub-MeV dark matter freeze-in
Cora Dvorkin, Tongyan Lin, Katelin Schutz
Dark matter (DM) could be a relic of freeze-in through a light mediator, where the DM is produced by extremely feeble, IR-dominated processes in the thermal Standard Model plasma.…
The Subhalo Mass Function and Ultralight Bosonic Dark Matter
Katelin Schutz
Warm dark matter has recently become increasingly constrained by observational inferences about the low-mass end of the subhalo mass function, which would be suppressed by dark mat…
Gravitational wave probes of dark matter: challenges and opportunities
Gianfranco Bertone, Djuna Croon, Mustafa A. Amin +9
In this white paper, we discuss the prospects for characterizing and identifying dark matter using gravitational waves, covering a wide range of dark matter candidate types and sig…
Cosmological Probes of Dark Matter Interactions: The Next Decade
Vera Gluscevic, Yacine Ali-Haimoud, Keith Bechtol +16
Cosmological observations offer unique and robust avenues for probing the fundamental nature of dark matter particles-they broadly test a range of compelling theoretical scenarios,…
Messengers from the Early Universe: Cosmic Neutrinos and Other Light Relics
Daniel Green, Mustafa A. Amin, Joel Meyers +136
The hot dense environment of the early universe is known to have produced large numbers of baryons, photons, and neutrinos. These extreme conditions may have also produced other lo…
Pulsar timing can constrain primordial black holes in the LIGO mass window
Katelin Schutz, Adrian Liu
The recent discovery of gravitational waves from merging black holes has generated interest in primordial black holes as a possible component of the dark matter. In this paper, we…
The Trispectrum in the Effective Field Theory of Large Scale Structure
Daniele Bertolini, Katelin Schutz, Mikhail P. Solon +1
We compute the connected four point correlation function (the trispectrum in Fourier space) of cosmological density perturbations at one-loop order in Standard Perturbation Theory…
Non-Gaussian Covariance of the Matter Power Spectrum in the Effective Field Theory of Large Scale Structure
Daniele Bertolini, Katelin Schutz, Mikhail P. Solon +2
We compute the non-Gaussian contribution to the covariance of the matter power spectrum at one-loop order in Standard Perturbation Theory (SPT), and using the framework of the effe…
Multifield Inflation after Planck: Isocurvature Modes from Nonminimal Couplings
Katelin Schutz, Evangelos I. Sfakianakis, David I. Kaiser
Recent measurements by the {\it Planck} experiment of the power spectrum of temperature anisotropies in the cosmic microwave background radiation (CMB) reveal a deficit of power in…
