Gravothermal Evolution of Self-Interacting Dark Matter Halos across Knudsen Numbers
James Gurian, Suroor Seher Gandhi, Neal Dalal +1
If the dark matter self-interacts elastically via a light mediator, then at relative velocities above a scale dictated by particle physics parameters, the cross section scales…
Primordial Physics in the Nonlinear Universe: Revealing the oscillating halo bias from cosmological collider models
Dhayaa Anbajagane, Neal Dalal
The initial conditions of our Universe contain a wealth of information about the particle physics of very high energies. One such class of signatures, called cosmological colliders…
Breaking the -- degeneracy with the time evolution of tracer number counts
Caio B. de S. Nascimento, Neal Dalal
Constraining local primordial non-Gaussianity through scale-dependent bias requires an accurate determination of the PNG bias parameter , which is completely degenerate with $…
ESO White Paper on Intensity Interferometry: Cosmology, Fundamental Physics, Quantum Optics
Robin Kaiser, William Guerin, Farrokh Vakili +21
In this whitepaper, we outline how recent technological advances and ongoing developments open qualitatively new science opportunities in cosmology, fundamental physics, and quantu…
Probing Dark Energy Microphysics with kSZ Tomography
Julius Adolff, Selim Hotinli, Neal Dalal
The accelerated expansion of the Universe is well established by geometric probes, yet its physical origin remains poorly understood. Most constraints on dark energy arise from bac…
Determining the Hubble Constant through Cross-Correlation of Galaxies and Gravitational Waves
Jiaming Pan, Dragan Huterer, Camille Avestruz +4
Gravitational wave (GW) standard sirens have the potential to measure the Hubble constant in the local universe independently of the distance ladder, and thus offer unique ne…
Updated bounds on ultra-light dark matter from the tiniest galaxies
Simon May, Neal Dalal, Andrey Kravtsov
The particle mass of dark matter (DM) was previously constrained using kinematics of ultra-faint dwarf galaxies to . This constraint, which excl…
Estimating non-gaussian bias using counts of tracers
Neal Dalal, Will J. Percival
Local-type primordial non-gaussianity generates a distinctive term in the clustering of tracers of large-scale structure, behaving as at small wavenumbers . In order to…
Probing and resolving AGN disks with ultrafast photon counters
Neal Dalal, Marios Galanis, Charles Gammie +2
Intensity interferometry is a technique developed many decades ago, that has recently enjoyed a renaissance thanks in part to advances in photodetector technology. We investigate t…
