Limits on dark matter, ultralight scalars, and cosmic neutrinos with gyroscope spin and precision clocks
Sara Rufrano Aliberti, Gaetano Lambiase, Tanmay Kumar Poddar
Dark matter (DM) within the solar system induces deviations in the geodetic drift of gyroscope spin due to its gravitational interaction. Assuming a constant DM density as a minima…
Pulsar Kick: Status and Perspective
Gaetano Lambiase, Tanmay Kumar Poddar
The high speeds seen in rapidly rotating pulsars after supernova explosions present a longstanding puzzle in astrophysics. Numerous theories have been suggested over the years to e…
Searching for New Physics in Ultradense Environment: a Review on Dark Matter Admixed Neutron Stars
Francesco Grippa, Gaetano Lambiase, Tanmay Kumar Poddar
Neutron Stars (NSs), among the densest objects in the Universe, are exceptional laboratories for investigating Dark Matter (DM) properties. Recent theoretical and observational dev…
Scalar and vector dark matter admixed neutron stars with linear and quadratic couplings
Francesco Grippa, Gaetano Lambiase, Tanmay Kumar Poddar
We investigate the effects of dark scalar- and vector-mediated interactions on dark matter admixed neutron stars, employing the two-fluid formalism. We adopt three different nuclea…
Constraints on electrophilic scalar coupling from rotating magnetized stars and effects of cosmic neutrino background
Gaetano Lambiase, Tanmay Kumar Poddar
An ultralight electrophilic scalar field can produce a long-range Yukawa-like spatial profile around a rotating, magnetized star when coupled to the constant number density of elec…
