Measurements of the Expansion Velocities of Ionized-Gas Superbubbles in Nearby Galaxies Based on Integral Field Spectroscopy Data
AbstractThe study of dynamic properties of bubbles in the interstellar medium is important for understanding the feedback mechanisms from...

Cosmic-Ray Acceleration by Supernova Remnants: Introduction and Theory
In 1934, in the same year that Baade and Zwicky (Proc Natl Acad Sci 20:259, 1934a) first established that there exist a class of very bright novae,...

Isolated Neutron Stars
Non-accreting neutron stars display diverse characteristics, leading us to classify them into several groups. This chapter is an observational driven...

Black Holes in Galaxy Mergers
Here we report on simulations which, for the first time, simultaneously track star formation and black hole growth, and associated feedback...

Middle-Aged and Old Supernova Remnants
A couple of thousand years after the explosion supernova remnants have swept up considerably more mass than the mass of the supernova ejecta.

SN 2019edo: A Type II-P Supernova with a Fast Brightness Rise and a Short Plateau Phase
AbstractWe present the results of BVRI photometry for the type II-P supernova (SN) 2019edo in NGC 4162 obtained from April 29, 2019, to January 26,...

Dark gauge boson production from neutron stars via nucleon-nucleon bremsstrahlung
We discuss the dark gauge boson emission from neutron stars via nucleon-nucleon bremsstrahlung. Through the rigorous treatment of the effective field...

An extremely energetic supernova from a very massive star in a dense medium
The interaction of a supernova with a circumstellar medium (CSM) can dramatically increase the emitted luminosity by converting kinetic energy to...
