Ultra-light dark matter is a class of dark matter models (DM), where DM is composed by bosons with masses ranging from $$10^{-24}\, \mathrm {eV}< m < \mathrm {eV}$$ 10 - 24 eV < m < eV . These models have been receiving a lot of attention in the past few years given their interesting property of forming a Bose–Einstein condensate (BEC) or a superfluid on galactic scales. BEC and superfluidity are some of the most striking quantum mechanical phenomena that manifest on macroscopic scales, and…

Closing the window on fuzzy dark matter with the 21cm signal
• Physics
• 2022
Fuzzy dark matter (FDM) is a well motivated candidate for dark matter (DM) as its tiny mass and large de-Broglie wavelength suppress small-scale matter ﬂuctuations, thereby solving some of the
Observational constraint on axion dark matter with gravitational waves
• Physics
• 2022
Most matter in the Universe is invisible and unknown, which is called dark matter. A candidate of dark matter is axion, which is an ultra-light particle motivated as a solution for the CP problem.
A geometric mechanism of vacuum energy cancellation
• Physics
• 2022
We explore a mechanism of geometric cancellation of vacuum energy zero-point ﬂuctuations, resolving de facto the cosmological constant problem. To do so, we assume at primordial times that vacuum
Ultra-Light Pion (ULP) and Baryon WIMPzilla Dark Matter
• Physics
• 2022
We consider a dark conﬁning gauge theory with millicharged Ultra-Light Pions (ULP) and heavy baryons as dark matter candidates. The model simultaneously realizes the ultra-light (STrongly-interacting
Cosmology-friendly time-varying neutrino masses via the sterile neutrino portal
• Physics
Physical Review D
• 2022
We investigate a consistent scenario of time-varying neutrino masses, and discuss its impact on cosmology, beta decay, and neutrino oscillation experiments. Such time-varying masses are assumed to be

The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders about the fundamental theory of nature at play in the extreme gravity regime, where the gravitational interaction is
Subsonic accretion and dynamical friction for a black hole moving through a self-interacting scalar dark matter cloud
• Physics
Physical Review D
• 2022
We investigate the ﬂow around a black hole moving through a cloud of self-interacting scalar dark matter. We focus on the large scalar mass limit, with quartic self-interactions, and on the subsonic
From a microscopic inertial active matter model to the Schr\"odinger equation
• Physics
• 2022
Field theories for the one-body density of an active ﬂuid, such as the paradigmatic active model B+, are simple yet very powerful tools for describing phenomena such as motility-induced phase
Searching for axion-like time-dependent cosmic birefringence with SPT-3G
• Biology
• 2022
Observations of the cosmic microwave background from SPT-3G, the current receiver on the South Pole Telescope, are used to set upper limits on the value of the axion-photon coupling constant g φγ over the approximate mass range, corresponding to oscillation periods from 12 hours to 100 days.
