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 ...

The Earliest Stage of Galactic Star Formation
The Astrophysical Journal Letters, 2023 Using a recently developed technique to estimate gas temperatures ( T _SF ) in star-forming regions from large photometric surveys, we propose a diagram, analogous to the Hertzsprung–Russell diagram for individual stars, to probe the evolution of ...

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

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.

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.

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 ...

The Astrophysical Journal Letters, 2023 We present the results of 0.″6-resolution observations of CO J = 3 − 2 line emission in 10 massive star-forming galaxies at z ∼ 2.2–2.5 with the Atacama Large Millimeter/submillimeter Array (ALMA).

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 ...

On the Origins of Starburst and Poststarburst Galaxies in Nearby Clusters [PDF]
The Astronomical Journal, 1999 HST WFPC2 images in B (F450W) and I (F814W) have been obtained for three starburst (SB) and two post-starburst (PSB) galaxies in the Coma cluster, and for three such galaxies in the cluster DC2048-52. V (F555W) and I images for an additional PSB galaxy in Coma have been extracted from the archive. Seven of these galaxies were previously classified as E/

A POPULATION OF INTERMEDIATE-MASS BLACK HOLES IN DWARF STARBURST GALAXIES UP TO REDSHIFT = 1.5 [PDF]
, 2015 We study a sample of ∼50,000 dwarf starburst and late-type galaxies drawn from the COSMOS survey with the aim of investigating the presence of nuclear accreting black holes (BHs) as those seed BHs from which supermassive BHs could grow in the early ...
