Starbursts in Isolated Galaxies? [PDF]

open access: yesAIP Conference Proceedings, 2005
I investigated the evolution of star forming dwarf galaxies by means of a one-zone model extended for dynamical evolution. This allows for a coupling between the dynamical state of the galaxy and its internal properties like star formation activity or the thermal state of the interstellar medium (ISM). The presented work focusses on the star formation (

Starburst Nuclei and Cosmic-Rays Transport Mechanisms: Future Opportunities for Neutrino Astronomy and Beyond Standard Model Studies [PDF]

open access: yesEPJ Web of Conferences, 2023
Experimental observations have demonstrated a strong correlation between star-forming processes and gamma-ray luminosities, giving strong hints about the nature of the Cosmic-Rays (CRs) transport mechanisms inside Starburst Nuclei.

X-ray emission of galaxies with emission lines

open access: yesВісник Астрономічної школи, 2011
We built new sample of 315 SDSS galaxies which were detected as X-ray sources in 2XMM catalog. On the basis of distribution of relative intensities of emission lines NII [6583] and OIII [5007] we divided objects of the sample into starburst galaxies and ...

An Extremely Compact, Low-mass Galaxy on its Way to Quiescence at z = 5.2

open access: yesThe Astrophysical Journal Letters, 2023
We report the discovery of a low-mass z = 5.200 ± 0.002 galaxy that is in the process of ceasing its star formation. The galaxy, MACS0417-z5BBG, is multiply imaged with magnification factors ∼40 by the galaxy cluster MACS J0417.5-1154, observed as part ...

DIRECT DETECTION OF LYMAN CONTINUUM ESCAPE FROM LOCAL STARBURST GALAXIES WITH THE COSMIC ORIGINS SPECTROGRAPH [PDF]

open access: yes, 2016
We report on the detection of Lyman continuum radiation in two nearby starburst galaxies. Tol 0440-381, Tol 1247-232, and Mrk 54 were observed with the Cosmic Origins Spectrograph on board the Hubble Space Telescope.

Massive post-starburst galaxies at z > 1 are compact proto-spheroids [PDF]

open access: yes, 2017
We investigate the relationship between the quenching of star formation and the structural transformation of massive galaxies, using a large sample of photometrically-selected poststarburst galaxies in the UKIDSS UDS field.

Methods for identifying high‐redshift galaxy cluster candidates

open access: yesAstronomische Nachrichten, Volume 340, Issue 7, Page 618-621, August 2019., 2019
Abstract Recent theories linked long gamma ray bursts (GRBs) to galaxies with rapid star formation or starburst; thus, we expect that long GRBs (LGRBs) are more frequent in midcluster galaxies where mergers and tidal interactions between gas‐rich galaxies are more likely to occur. Yet there is no galaxy cluster known to be associated with LGRBs.

Sensitivity of the combined fit of energy spectrum, shower depth distributions, and arrival directions at the Pierre Auger Observatory [PDF]

open access: yesEPJ Web of Conferences, 2023
The Pierre Auger Observatory measures several characteristics of ultra-high-energy cosmic rays (UHECRs), most importantly the energy spectrum, the distribution of maximum shower depths and the arrival directions.

The History of Starburst Galaxies [PDF]

open access: yes, 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.
