The Colors and Sizes of Recently Quenched Galaxies: A Result of Compact Starburst before Quenching [PDF]

Astrophysical Journal, 2019
We analyze the colors and sizes of 32 quiescent (UVJ-selected) galaxies with strong Balmer absorption (EW(Hδ) ≥ 4 Å) at z ∼ 0.8 drawn from DR2 of the LEGA-C survey to test the hypothesis that these galaxies experienced compact, central starbursts before ...

Estimation of the detected background by the future gamma ray transient mission CAMELOT

Astronomische Nachrichten, Volume 340, Issue 7, Page 666-673, August 2019., 2019
Abstract This study presents a background estimation for the CubeSats Applied for MEasuring and LOcalising Transients (CAMELOT), which is a proposed fleet of nanosatellites for the all‐sky monitoring and timing‐based localization of gamma ray transients with precise localization capability at low Earth orbits.

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 ...

Gasdynamics and Starbursts in Interacting Galaxies [PDF]

Symposium - International Astronomical Union, 1999
The onset of gaseous inflows and central activity in interacting galaxies is driven largely by induced bars in the host galaxies. The stability of galaxies against growing bar modes is a direct function of their structural properties — galaxies with central bulges or low disk surface densities are more stable against central starbursts than are ...

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 ...

Star Formation Law at Sub‐kpc Scale in the Elliptical Galaxy Centaurus A as Seen by ALMA

Advances in Astronomy, Volume 2017, Issue 1, 2017., 2017
We present an extensive analysis of the relationship between star formation rate surface density (∑SFR) and molecular gas surface density (∑H2) at sub‐kpc scale in the elliptical galaxy Centaurus A (also known as NGC 5128) at the distance 3.8 Mpc. 12CO (J = 2‐1) data from Atacama Large Millimetre/Sub‐Millimetre Array SV data with very high resolution ...

The Evolutionary Sequence of Post-Starburst Galaxies [PDF]

, 2017
© 2017 The Authors. There are multiple ways in which to select post-starburst galaxies in the literature. In this work, we present a study into how two well-used selection techniques have consequences on observable post-starburst galaxy parameters, such ...

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.

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).
