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…
The Novel Probes Project -- Tests of Gravity on Astrophysical Scales
Tessa Baker, Alexandre Barreira, Harry Desmond +8
We introduce The Novel Probes Project, an initiative to advance the field of astrophysical tests of the dark sector by creating a forum that connects observers and theorists. This…
A local resolution of the Hubble tension: The impact of screened fifth forces on the cosmic distance ladder
Harry Desmond, Bhuvnesh Jain, Jeremy Sakstein
The discrepancy between the values of the Hubble constant derived from the local distance ladder and the cosmic microwave background provides a tantalising hint of new physic…
Screened Fifth Forces Mediated by Dark Matter-Baryon Interactions: Theory and Astrophysical Probes
Jeremy Sakstein, Harry Desmond, Bhuvnesh Jain
We derive the details of a new screening mechanism where the interactions of baryons and dark matter can be screened according to the local dark matter density. In this mechanism,…
Constraints on Chameleon f(R)-Gravity from Galaxy Rotation Curves of the SPARC Sample
Aneesh P. Naik, Ewald Puchwein, Anne-Christine Davis +2
In chameleon -gravity, the fifth force will lead to `upturns' in galaxy rotation curves near the screening radius. The location of the upturn depends on the cosmic background…
Screened fifth forces in parity-breaking correlation functions
Darsh Kodwani, Harry Desmond
Cross-correlating two different types of galaxy gives rise to parity breaking in the correlation function that derives from differences in the galaxies' properties and environments…
The baryonic Tully-Fisher relation for different velocity definitions and implications for galaxy angular momentum
Federico Lelli, Stacy S. McGaugh, James M. Schombert +2
We study the baryonic Tully-Fisher relation (BTFR) at z=0 using 153 galaxies from the SPARC sample. We consider different definitions of the characteristic velocity from HI and H-a…
