A search for candidate radio supernova remnants in the nearby irregular starburst galaxies NGC 4214 and NGC 4395 [PDF]
Serbian Astronomical Journal, 2005 We present the results of a search for new candidate radio supernova remnants (SNRs) in the nearby starburst irregular galaxies NGC 4214 and NGC 4395 using archived radio observations made with the Very Large Array (VLA) at the wavelengths of 3.5 cm, 6 ...

Starbursts in barred spiral galaxies [PDF]
Astronomy and Astrophysics Supplement Series, 1998 This paper presents optical long-slit spectroscopic observations of 105 barred Markarian IRAS galaxies. These observations are used to determine the spectral type of emission-line regions in the nucleus and along the bar of the galaxies, in order to define a homogeneous sample of Starburst Nucleus Galaxies (SBNGs). Our selection criteria have been very

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.

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 History of Starburst Galaxies [PDF]
, 2001 Dusty galaxies with luminosities in excess of 10^11 solar luminosities have been detected out to redshifts of about unity by the Infrared Space Observatory (ISO), and to higher redshifts using millimetre(mm)- and submm-wave cameras on ground-based telescopes.

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.

Superwinds and the nature of starburst galaxies [PDF]
Symposium - International Astronomical Union, 1999 I discuss the observational evidence that starburst galaxies are able to drive galactic-scale outflows ('superwinds') and then argue generally that superwinds must have had an important role in galaxy evolution. To explore the role of feedback from massive stars, I review results suggesting that starbursts seem to obey a limiting IR surface brightness ...

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 ...

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.
