The Observer’s Guide to the Gamma‐Ray Burst Supernova Connection

Advances in Astronomy, Volume 2017, Issue 1, 2017., 2017
We present a detailed report of the connection between long‐duration gamma‐ray bursts (GRBs) and their accompanying supernovae (SNe). The discussion presented here places emphasis on how observations, and the modelling of observations, have constrained what we know about GRB‐SNe.

Chronos and KAIROS: MOSFIRE observations of post-starburst galaxies in z ∼ 1 clusters and groups [PDF]

, 2016
We present an exploration of ∼500 spectroscopically confirmed galaxies in and around two large-scale structures (LSSs) at z ∼ 1 drawn from the Observations of Redshift Evolution in Large Scale Environments survey, an ongoing, wide-field photometric and ...

Growth of Accreting Supermassive Black Hole Seeds and Neutrino Radiation

Journal of Astrophysics, Volume 2015, Issue 1, 2015., 2015
In the framework of microscopic theory of black hole (MTBH), which explores the most important processes of rearrangement of vacuum state and spontaneous breaking of gravitation gauge symmetry at huge energies, we have undertaken a large series of numerical simulations with the goal to trace an evolution of the mass assembly history of 377 plausible ...

AGN/Starburst Connection

Acta Polytechnica CTU Proceedings, 2014
Two main physical processes characterize the activity in the nuclear region of active galaxies: an intense star formation (starburst, SB) and an Active Galactic Nucleus (AGN).

What triggers galaxy transformations? The environments of post-starburst galaxies [PDF]

, 2006
(abridged) There are good observational reasons to believe that the progenitors of red galaxies have undergone starbursts, followed by a post-starburst phase.

UGC 7639: A Dwarf Galaxy in the Canes Venatici I Cloud

Advances in Astronomy, Volume 2015, Issue 1, 2015., 2015
We want to get insight into the formation mechanism and the evolution of UGC 7639, a dwarf galaxy in the Canes Venatici I Cloud (CVnIC). We used archival multiwavelength data to constrain its global properties. Ultraviolet images show that UGC 7639 inner regions are composed mostly by young stellar populations.

GOALS-JWST: Mid-infrared Spectroscopy of the Nucleus of NGC 7469

The Astrophysical Journal Letters, 2023
We present mid-infrared spectroscopic observations of the nucleus of the nearby Seyfert galaxy NGC 7469 taken with the MIRI instrument on the James Webb Space Telescope (JWST) as part of Directors Discretionary Time Early Release Science program 1328 ...

Welcome to the Twilight Zone: The Mid-infrared Properties of Post-starburst Galaxies [PDF]

, 2016
We investigate the optical and Wide-field Survey Explorer (WISE) colors of “E+A” identified post-starburst galaxies, including a deep analysis of 190 post-starbursts detected in the 2 μm All Sky Survey Extended Source Catalog. The post-starburst galaxies

Imaging FTS: A Different Approach to Integral Field Spectroscopy

Advances in Astronomy, Volume 2014, Issue 1, 2014., 2014
Imaging Fourier transform spectroscopy (iFTS) is a promising, although technically very challenging, option for wide‐field hyperspectral imagery. We present in this paper an introduction to the iFTS concept and its advantages and drawbacks, as well as examples of data obtained with a prototype iFTS, SpIOMM, attached to the 1.6 m telescope of the ...
