Radio and γ-ray Evidence for the Supernova Origin of High-velocity Cloud Complex M

The Astrophysical Journal, 2023
Using λ 21 cm galactic neutral hydrogen data from the HI4PI survey and 0.75–30 MeV γ -ray emission from the Imaging Compton Telescope, we have searched for the origin event that accelerated high-velocity cloud Complex M.

The MEGA Advanced Compton Telescope Project [PDF]

, 2001
The goal of the Medium Energy Gamma-ray Astronomy (MEGA) telescope is to improve sensitivity at medium gamma-ray energies (0.4-50 MeV) by at least an order of magnitude over that of COMPTEL. This will be achieved with a new compact design that allows for

A Stochastic Approach to Reconstruct Gamma-Ray-burst Light Curves

The Astrophysical Journal Supplement Series, 2023
Gamma-ray bursts (GRBs), as they are observed at high redshift ( z = 9.4), are vital to cosmological studies and investigating Population III stars. To tackle these studies, we need correlations among relevant GRB variables with the requirement of small ...

Gamma-ray astronomy

Nuclear Physics News, 2001
This paper summarizes recents results in gamma-ray astronomy, most of which were derived with data from ground-based gamma-ray detectors. Many of the contributions presented at this conference involve multiwavelength studies which combine ground-based gamma-ray measurements with optical data or space-based X-ray and gamma-ray measurements.

Gamma-Rays as Probes for the Multi-Dimensionality of Type Ia Supernovae [PDF]

, 2001
We present $\gamma $-ray spectra for a set of Type Ia supernovae models. Our study is based on a detailed Monte Carlo transport scheme for both spherical and full 3-D geometries.
