A New Probe of Dark Matter Subhalos: Stellar Aberration with TESS
Matthias Daniel, Xiao Xue, Kris Pardo +1
Small-scale dark matter (DM) structure encodes key information about the particle nature of DM and therefore provides a sensitive test of competing models. Yet, it remains hidden f…
The Atacama Cosmology Telescope: A Test of the Gravitational Force Law on Cosmological Scales Using the Kinematic Sunyaev-Zeldovich Effect
Patricio A. Gallardo, Kris Pardo, Oliver H. E. Philcox +38
The mean pairwise velocity of massive halos reflects the gravitational force law on cosmic scales. We combine cosmic microwave background intensity maps from the Atacama Cosmology…
Sensitivity of Weak Lensing Surveys to Gravitational Waves from Inspiraling Supermassive Black Hole Binaries
Tal Adi, Kris Pardo, Olivier Doré
We explore the sensitivity of weak lensing surveys to gravitational waves (GWs) emitted by inspiraling supermassive black hole binaries (SMBHBs) in the nanohertz to microhertz freq…
Constraints on the dark matter-baryon interaction cross section from galaxy cluster thermodynamics
Eleanor Stuart, Kris Pardo
Dark matter (DM) models with a non-zero DM-baryon interaction cross section imply energy transfer between DM and baryons. We present a new method of constraining the DM-baryon inte…
Detecting dark matter subhalos with the Nancy Grace Roman Space Telescope
Kris Pardo, Olivier Doré
The dark matter subhalo mass function is a promising way of distinguishing between dark matter models. While cold dark matter predicts halos down to Earth-sized masses, other dark…
What is the price of abandoning dark matter? Cosmological constraints on alternative gravity theories
Kris Pardo, David N. Spergel
Any successful alternative gravity theory that obviates the need for dark matter must fit our cosmological observations. Measurements of microwave background polarization trace the…
Testing self-interacting dark matter with galaxy warps
Kris Pardo, Harry Desmond, Pedro G. Ferreira
Self-interacting dark matter (SIDM) is an able alternative to collisionless dark matter. If dark matter does have self-interactions, we would expect this to cause a separation betw…
Modified Gravity and Dark Energy models Beyond CDM Testable by LSST
Mustapha Ishak, Tessa Baker, Philip Bull +8
One of the main science goals of the Large Synoptic Survey Telescope (LSST) is to uncover the nature of cosmic acceleration. In the base analysis, possible deviations from the Lamb…
Testing Emergent Gravity with Isolated Dwarf Galaxies
Kris Pardo
Verlinde (2016) has proposed a new modified theory of gravity, Emergent Gravity (EG), as an alternative to dark matter. EG reproduces the Tully-Fisher relationship with no free par…
