Probing imperfect axions with nuclear clocks
Salvatore Bottaro, Andrea Caputo, Gilad Perez +2
We show that Th nuclear clocks can probe departures from the Peccei-Quinn (PQ) solution to the strong CP problem. Explicit PQ breaking or additional CP-violating interactio…
Influence of tides and self-gravity on Ultra-Light Dark Matter Bounds from Dwarf Galaxies
Andrea Caputo, Luca Teodori
Dwarf spheroidal galaxies provide some of the most sensitive astrophysical probes of ultra-light dark matter (ULDM), but the inferred constraints can be affected by two important s…
The DREAMS Project: Disentangling the Impact of Halo-to-Halo Variance and Baryonic Feedback on Milky Way Dark Matter Density Profiles
Alex M. Garcia, Jonah C. Rose, Paul Torrey +23
In this work, we utilize a new suite of Milky Way-mass halos from the DREAMS Project, simulated with Cold Dark Matter (CDM), to quantify the influence of baryon feedback and intrin…
Ultra-Light Dark Matter Simulations and Stellar Dynamics: Tension in Dwarf Galaxies for eV
Luca Teodori, Andrea Caputo, Kfir Blum
We present numerical simulations of dark matter and stellar dynamics in ultra light dark matter halos tailored to mimic dwarf galaxies. An important effect we observe is the dynami…
Constraints on dark photon dark matter from Lyman- forest simulations and an ultra-high signal-to-noise quasar spectrum
Andrea Trost, James S. Bolton, Andrea Caputo +3
The ultralight dark photon is a well-motivated, hypothetical dark matter candidate. In a dilute plasma, they can resonantly convert into photons, and heat up the intergalactic medi…
Shaping Dark Photon Spectral Distortions
Giorgi Arsenadze, Andrea Caputo, Xucheng Gan +2
The cosmic microwave background (CMB) spectrum is an extraordinary tool for exploring physics beyond the Standard Model. The exquisite precision of the measurement makes it particu…
On the sensitivity of nuclear clocks to new physics
Andrea Caputo, Doron Gazit, Hans-Werner Hammer +4
The recent demonstration of laser excitation of the eV isomeric state of Thorium-229 is a significant step towards a nuclear clock. The low excitation energy likely res…
Neutrino emission in cold neutron stars: Bremsstrahlung and modified urca rates reexamined
Salvatore Bottaro, Andrea Caputo, Damiano Fiorillo
Neutrino emission in cold neutron stars is dominated by the modified urca (murca) process and nucleon-nucleon bremsstrahlung. The standard emission rates were provided by Friman an…
Introducing the DREAMS Project: DaRk mattEr and Astrophysics with Machine learning and Simulations
Jonah C. Rose, Paul Torrey, Francisco Villaescusa-Navarro +27
We introduce the DREAMS project, an innovative approach to understanding the astrophysical implications of alternative dark matter models and their effects on galaxy formation and…
