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…

Listening to dark sirens from gravitational waves:\it{Combined effects of fifth force, ultralight particle radiation, and eccentricity}
Tanmay Kumar Poddar, Anish Ghoshal, Gaetano Lambiase
We derive in detail the orbital period loss of a compact binary system in presence of a fifth force and radiation of ultralight particles for a general eccentric Keplerian orbit. W…
