The information content of optical intensity interferometry

Neal Dalal, Biwei Dai, Matthew K. Browning

Optical intensity interferometry (II) can in principle resolve structure on angular scales , but it measures only the squared visibility , discarding Fouri…

Tomography of the gamma-ray sky from cross-correlation with DESI DR2 and unWISE galaxies

Alex Krolewski, Neal Dalal, Will J. Percival +39

We study the origin of extragalactic gamma-ray emission observed by Fermi-LAT, using the cross-correlation of the gamma-ray sky with maps of large-scale structure provided by the D…

Velocity profiles of matter and biased tracers around voids

Elena Massara, Will J. Percival, Neal Dalal +4

The velocity profile of galaxies around voids is a key ingredient for redshift space distortion (RSD) measurements made using the void-galaxy correlation function. In this paper we…

Not so fuzzy: excluding FDM with sizes and stellar kinematics of ultra-faint dwarf galaxies

Neal Dalal, Andrey Kravtsov

We use observations of ultra-faint dwarf (UFD) galaxies to constrain the particle mass of ultra-light dark matter. Potential fluctuations created by wave interference in virialized…

Beyond Mass: Detecting Secondary Halo Properties with Galaxy-Galaxy Lensing

Enia Xhakaj, Alexie Leauthaud, Johannes Lange +3

Secondary halo properties beyond mass, such as the mass accretion rate (MAR), concentration, and the half mass scale, are essential in understanding the formation of large-scale st…

Don't cross the streams: caustics from Fuzzy Dark Matter

Neal Dalal, Jo Bovy, Lam Hui +1

We study how tidal streams from globular clusters may be used to constrain the mass of ultra-light dark matter particles, called `fuzzy' dark matter (FDM). A general feature of FDM…
