Shimmering gravitons in the gamma-ray sky
Sabir Ramazanov, Rome Samanta, Georg Trenkler +1
What is the highest energy at which gravitons can be observed? We address this question by studying graviton-to-photon conversion - the inverse-Gertsenshtein effect - in the magnet…
PBH-infused seesaw origin of matter and unique gravitational waves
Debasish Borah, Suruj Jyoti Das, Rome Samanta +1
The Standard Model, extended with three right-handed (RH) neutrinos, is the simplest model that can explain light neutrino masses, the baryon asymmetry of the Universe, and dark ma…
Probing ultralight scalar, vector and tensor dark matter with pulsar timing arrays
Caner Unal, Federico R. Urban, Ely D. Kovetz
Pulsar timing arrays (PTAs) are sensitive to oscillations in the gravitational potential along the line-of-sight due to ultralight particle pressure. We calculate the probing power…
First High-speed Video Camera Observations of a Lightning Flash Associated with a Downward Terrestrial Gamma-ray Flash
R. U. Abbasi, M. M. F. Saba, J. W. Belz +146
In this paper, we present the first high-speed video observation of a cloud-to-ground lightning flash and its associated downward-directed Terrestrial Gamma-ray Flash (TGF). The op…
Constraining ultra-high-energy cosmic ray composition through cross-correlations
Konstantinos Tanidis, Federico R. Urban, Stefano Camera
The chemical composition of the highest end of the ultra-high-energy cosmic ray spectrum is very hard to measure experimentally, and to this day it remains mostly unknown. Since th…
Testing Super-Heavy Dark Matter from Primordial Black Holes with Gravitational Waves
Rome Samanta, Federico R. Urban
Ultra-light primordial black holes with masses ~g evaporate before big-bang nucleosynthesis producing all matter fields, including dark matter, in particular super-hea…
