Design concepts for the Cherenkov Telescope Array CTA: an advanced facility for ground-based high-energy gamma-ray astronomy
Ground-based gamma-ray astronomy has had a major breakthrough with the impressive results obtained using systems of imaging atmospheric Cherenkov telescopes. Ground-based gamma-ray astronomy has a
Testing the hadronuclear origin of PeV neutrinos observed with IceCube
We consider implications of the IceCube signal for hadronuclear (pp) scenarios of neutrino sources such as galaxy clusters/groups and star-forming galaxies. Since the observed neutrino flux is
A burst in a wind bubble and the impact on baryonic ejecta: high-energy gamma-ray flashes and afterglows from fast radio bursts and pulsar-driven supernova remnants
Tenuous wind bubbles, which are formed by the spin-down activity of central compact remnants, are relevant in some models of fast radio bursts (FRBs) and super-luminous supernovae. We study their
Diffuse Neutrino Intensity from the Inner Jets of Active Galactic Nuclei: Impacts of External Photon Fields and the Blazar Sequence
We study high-energy neutrino production in inner jets of radio-loud active galactic nuclei (AGN), taking into account effects of external photon fields and the blazar sequence. We show that the
Constraining High-Energy Cosmic Neutrino Sources: Implications and Prospects
We consider limits on the local (z=0) density (n0) of extragalactic neutrino sources set by the nondetection of steady high-energy neutrino sources producing ≳50  TeV muon multiplets in the present
Science with the Cherenkov Telescope Array
The Cherenkov Telescope Array, CTA, will be the major global observatory for very high energy gamma-ray astronomy over the next decade and beyond. The scientific potential of CTA is extremely broad:
The spectra of BL Lac objects and Fanaroff-Riley I radio galaxies are commonly explained by the one-zone leptonic synchrotron self-Compton (SSC) model. Spectral modeling of correlated multiwavelength
TeV-PeV neutrinos from low-power gamma-ray burst jets inside stars.
It is found that ultralong GRBs avoid constraints and detecting the TeV signal will support giant progenitors, and predictions for low-power GRB classes including low-luminosity GRBs can be consistent with the astrophysical neutrino background IceCube may detect.
γ-ray Constraints on Decaying Dark Matter and Implications for IceCube.
Some of the strongest constraints to date on the dark matter (DM) lifetime in the mass range from hundreds of MeV to above an EeV are derived and a decaying DM interpretation for the 10 TeV-1 PeV neutrino flux observed by IceCube is disfavored by these constraints.
