GrAviPaSt’s Lens to the Past: Unveiling the Evolution of Filamentary Structures

open access: yesThe Astrophysical Journal
This paper examines the evolution of cosmic filaments across redshifts 1, 0.5, and 0 using the IllustrisTNG100-1 magnetohydrodynamical simulation. To achieve this, we introduce GrAviPaSt, a simple, efficient, and parameter-free filament identification ...

Highlights from the Telescope Array

open access: yesEPJ Web of Conferences, 2016
The Telescope Array measures the properties of ultra high energy cosmic ray induced extensive air showers. We do this using a variety of techniques including an array of scintillator detectors to sample the footprint of the air shower when it reaches the

Long-lived biνo at the LHC

open access: yesJournal of High Energy Physics, 2021
We examine the detection prospects for a long-lived biνo, a pseudo-Dirac bino which is responsible for neutrino masses, at the LHC and at dedicated long-lived particle detectors.

Soft bootstrap and effective field theories

open access: yesJournal of High Energy Physics, 2019
The soft bootstrap program aims to construct consistent effective field theories (EFT’s) by recursively imposing the desired soft limit on tree-level scattering amplitudes through on-shell recursion relations.

Intersecting surface defects and instanton partition functions

open access: yesJournal of High Energy Physics, 2017
We analyze intersecting surface defects inserted in interacting four-dimensional N = 2 $$ \mathcal{N}=2 $$ supersymmetric quantum field theories. We employ the realization of a class of such systems as the infrared fixed points of renormalization group ...

High-energy neutrino astronomy

open access: yesJournal of Physics: Conference Series, 2012
Neutrino astronomy, conceptually conceived four decades ago, has entered an exciting phase for providing results on the quest for the sources of the observed highest energy particles. IceCube and ANTARES are now completed and are scanning in space and time possible signals of high energy neutrinos indicating the existence of such sources.

High Energy Neutrino Astronomy: Status and Perspectives [PDF]

open access: yesAIP Conference Proceedings, 2008
The year 2008 has witnessed remarkable steps in developing high energy neutrino telescopes. IceCube at the South Pole has been deployed with 40 of its planned 80 strings and reached half a cubic kilometer instrumented volume, in the Mediterranean Sea the "first-stage" neutrino telescope ANTARES has been completed and takes data with 12 strings.

Baryogenesis in a parity solution to the strong CP problem

open access: yesJournal of High Energy Physics, 2023
Space-time parity can solve the strong CP problem and introduces a spontaneously broken SU(2) R gauge symmetry. We investigate the possibility of baryogenesis from a first-order SU(2) R phase transition similar to electroweak baryogenesis.

Testing loop quantum gravity by quasi-periodic oscillations: rotating blackholes

open access: yesEuropean Physical Journal C: Particles and Fields
We investigate a compelling model of a rotating black hole that is deformed by the effects of loop quantum gravity (LQG). We present a simplified metric and explore two distinct geometries: one in which the masses of the black hole and white hole are ...
