Atmospheric neutrino oscillations and tau neutrinos in ice [PDF]

open access: yes, 2010
The main goal of the IceCube Deep Core Array is to search for neutrinos of astrophysical origins. Atmospheric neutrinos are commonly considered as a background for these searches. We show here that cascade measurements in the Ice Cube Deep Core Array can

Slim accretion disks: theory and observational consequences

open access: yes, 2019
Slim accretion disks idea emerged over 30 years ago as an answer to several unsolved problems. Since that time there was a tremendous increase in the amount of observational data where this model applies.

Gamma Ray Constraints on Flavor Violating Asymmetric Dark Matter

open access: yes, 2012
We show how cosmic gamma rays can be used to constrain models of asymmetric Dark Matter decaying into lepton pairs by violating flavor. First of all we require the models to explain the anomalies in the charged cosmic rays measured by PAMELA, FERMI and ...

IceCube-Gen2: A Vision for the Future of Neutrino Astronomy in Antarctica [PDF]

open access: yes, 2014
The recent observation by the IceCube neutrino observatory of an astrophysical flux of neutrinos represents the "first light" in the nascent field of neutrino astronomy.

Measuring the neutron star equation of state using X-ray timing [PDF]

open access: yes, 2016
One of the primary science goals of the next generation of hard X-ray timing instruments is to determine the equation of state of the matter at supranuclear densities inside neutron stars, by measuring the radius of neutron stars with different masses to

Galaxy Clusters as Reservoirs of Heavy Dark Matter and High-Energy Cosmic Rays: Constraints from Neutrino Observations

open access: yes, 2013
Galaxy Clusters (GCs) are the largest reservoirs of both dark matter and cosmic rays (CRs). Dark matter self-annihilation can lead to a high luminosity in gamma rays and neutrinos, enhanced by a strong degree of clustering in dark matter substructures ...

Astroparticles in Latin America: current status and outlook

open access: yes, 2014
The successful installation and operation of the Pierre Auger Observatory in Argentina has been a milestone in Astroparticle research in Latin America, generating new regional research opportunities in the field.

Linear perturbations of low angular momentum accretion flow in the Kerr metric and the corresponding emergent gravity phenomena

open access: yes, 2018
For certain geometric configuration of matter falling onto a rotating black hole, we develop a novel linear perturbation analysis scheme to perform the stability analysis of stationary integral accretion solutions corresponding to the steady state low ...

Colloquium: Multimessenger astronomy with gravitational waves and high-energy neutrinos [PDF]

open access: yes, 2013
Many of the astrophysical sources and violent phenomena observed in our Universe are potential emitters of gravitational waves and high-energy cosmic radiation, including photons, hadrons, and presumably also neutrinos.

Event Horizon Telescope Observations as Probes for Quantum Structure of Astrophysical Black Holes

open access: yes, 2018
The need for a consistent quantum evolution for black holes has led to proposals that their semiclassical description is modified not just near the singularity, but at horizon or larger scales.
