Article: Limits to gauge coupling in the dark sector set by the non-observation of instanton-induced decay of Super-Heavy Dark Matter in the Pierre Auger Observatory data

Upper limits at 95\% C.L. on the effective coupling constant of a hidden gauge interaction as a function of the mass of a dark matter particle X decaying into quark/anti-quark…

Article: Predicted diffuse flux of ultra-high energy photons in the galactic plane; its implications for the search for super-heavy dark matter

Upper limits on diffuse photon fluxes for several energy thresholds, and expected fluxes from UHECRs interactions with the gas distribution in the Galaxy (grey dashed and blue dashed-dotted lines), as…

Search for Gravitational Waves Associated with Gamma-Ray Bursts Detected by Fermi and Swift During the LIGO-Virgo Run O3b

We search for gravitational-wave signals associated with gamma-ray bursts detected by the Fermi and Swift satellites during the second half of the third observing run of Advanced LIGO and Advanced…

GWTC-3: Compact Binary Coalescences Observed by LIGO and Virgo During the Second Part of the Third Observing Run

The LIGO and Virgo detectors have observed 35 new gravitational-wave events, between November 2019 and March 2020, during the second half of the third observing run (O3b). The total number…

Pre-merger Localization of Compact-binary Mergers with Third-generation Observatories

We present the prospects for the pre-merger detection and localization of binary neutron star mergers with third-generation gravitational-wave (GW) observatories. We consider a wide variety of GW networks that may…

Constraints on cosmic strings using data from the third Advanced LIGO-Virgo observing run

Abstract: (APS) We search for gravitational-wave signals produced by cosmic strings in the Advanced LIGO and Virgo full O3 dataset. Search results are presented for gravitational waves produced by cosmic…
