Cosmological Evidence for Dark Axion-Dark Baryon Interactions from Apparent Phantom Crossing
Justin Khoury, Meng-Xiang Lin, Mark Trodden
Interactions between dark matter and dark energy can lead to an apparent phantom-crossing behavior that mimics the expansion history preferred by the latest cosmological observatio…
Hidden symmetries for tidal Love numbers: Generalities and applications to analog black holes
Valerio De Luca, Brandon Khek, Justin Khoury +1
Tidal Love numbers characterize the conservative, static response of compact objects to external tidal fields. Remarkably, these quantities vanish identically for asymptotically fl…
Superfluid Dark Matter
Lasha Berezhiani, Giordano Cintia, Valerio De Luca +1
The superfluid dark matter model offers an elegant solution to reconcile discrepancies between the predictions of the cold dark matter paradigm and observations on galactic scales.…
Apparent and a Lower from Dark Axion and Dark Baryons Interactions
Justin Khoury, Meng-Xiang Lin, Mark Trodden
We show that a simple coupling between dark energy and dark matter can simultaneously address two distinct hints at new physics coming from cosmological observations. The first is…
Gravitational memory and Ward identities in the local detector frame
Valerio De Luca, Justin Khoury, Sam S. C. Wong
Gravitational memory, which describes the permanent shift in the strain after the passage of gravitational waves, is directly related to Weinberg's soft graviton theorems and the B…
Tidal Love numbers of analogue black holes
Valerio De Luca, Brandon Khek, Justin Khoury +1
Tidal Love numbers quantify the conservative static response of compact objects to external tidal fields, and are found to vanish exactly for asymptotically flat black holes in fou…
Gravitational memory and soft theorems: The local perspective
Valerio De Luca, Justin Khoury, Sam S. C. Wong
In general relativity, gravitational memory describes the lasting change in the separation and relative velocity of freely falling detectors after the passage of gravitational wave…
Tidal Love numbers and Green's functions in black hole spacetimes
Valerio De Luca, Alice Garoffolo, Justin Khoury +1
Tidal interactions play a crucial role in deciphering gravitational wave signals emitted by the coalescence of binary systems. They are usually quantified by a set of complex coeff…
Dynamical friction in dark matter superfluids: The evolution of black hole binaries
Lasha Berezhiani, Giordano Cintia, Valerio De Luca +1
The theory of superfluid dark matter is characterized by self-interacting sub-eV particles that thermalize and condense to form a superfluid core in galaxies. Massive black holes a…
