Chimneys in the starburst galaxy M 82 [PDF]
Symposium - International Astronomical Union, 1999 A new radio image of the core of the starburst galaxy M82 is presented. A pair of probable galactic chimneys are evident. Such structures have been conjectured to result when a giant shell of ionized gas breaks out of the dense plane of a galaxy and ejects hot gas into the halo.

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 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.

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 ...

An Explanation for the Overrepresentation of Tidal Disruption Events in Post-starburst Galaxies
The Astrophysical Journal, 2023 Tidal disruption events (TDEs) provide a valuable probe for studying the dynamics of stars in the nuclear environments of galaxies. Recent observations show that TDEs are strongly overrepresented in post-starburst or “green valley” galaxies, although the

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.

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 ...

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 ...

Chemodynamical Simulations of Dwarf Galaxy Evolution
Advances in Astronomy, Volume 2014, Issue 1, 2014., 2014 In this review I give a summary of the state of the art for what concerns the chemo‐dynamical numerical modelling of galaxies in general and of dwarf galaxies in particular. In particular, I focus my attention on (i) initial conditions, (ii) the equations to solve; (iii) the star formation process in galaxies, (iv) the initial mass function, (v) the ...
