Magnetization of the IGM by Starburst Dwarf Galaxies?
, 2011 It is well known that the intergalactic or intracluster medium (IGM, ICM) is pervaded by a weak magnetic field, along with a population of relativistic particles.

No Metallicity Preference in Fast Radio Burst Host Galaxies
The Astrophysical Journal LettersFast radio bursts (FRBs) are millisecond-duration extragalactic radio transients of unknown origin, and studying their host galaxies could offer clues to constrain progenitor models.

High-velocity outflows persist up to 1 Gyr after a starburst in recently quenched galaxies at z > 1
High-velocity outflows are ubiquitous in star-forming galaxies at cosmic noon, but are not as common in passive galaxies at the same epoch. Using optical spectra of galaxies selected from the UKIDSS Ultra Deep Survey at z > 1, we perform a stacking ...

Machine Learning Classification of COSMOS2020 Galaxies: Quiescent versus Star-forming
The Astrophysical JournalAccurately distinguishing between quiescent and star-forming galaxies is essential for understanding galaxy evolution. Traditional methods, such as spectral energy distribution (SED) fitting, can be computationally expensive and may struggle to capture ...

The Chemical Evolution of Galaxies by Successive Starbursts
, 1999 We propose an evolutionary scenario by successive bursts of star formation to reproduce the chemical properties of massive nearby Starburst Nucleus Galaxies (SBNGs). The N/O abundance ratios in SBNGs are 0.2 dex higher than in normal HII regions observed in the disks of late-type spirals.

Spatially resolved spectroscopy of faint star-forming galaxies & their environments in the high redshift universe [PDF]
, 2011 This thesis is concerned with the spectroscopic observations of distant galaxies, 1 < z < 5. The galaxies presented here are intrinsically faint such that their ux is dominated by ordinary star formation rather than galaxy-galaxy merging and/or ...

Theoretical Modeling of Starburst Galaxies
, 2002 We have modeled a large sample of infrared starburst galaxies using both the PEGASE v2.0 and STARBURST99 codes to generate the spectral energy distribution (SED) of the young star clusters.

The Cosmic Owl: Twin Active Collisional Ring Galaxies with Starburst Merging Front at z = 1.14
The Astrophysical JournalGalaxy mergers play a critical role in driving galaxy evolution, especially by transforming galaxy morphology, redistributing gas around galaxies, triggering active galactic nuclei (AGN), and stimulating star formation.

Revealing X-ray luminous AGN in apparent starburst galaxies
, 2010 It is commonly assumed in deep survey work that all galaxies with X-ray luminosities above about 1042ergs-1 harbour AGN, regardless of their optical spectrum, due to the absence of starburst galaxies in the local Universe reaching such extreme ...

Death by Impact: Evidence for Merger-driven Quenching in a Collisional Ring Galaxy at Cosmic Noon
The Astrophysical JournalThe role of interactions and mergers in the rapid quenching of massive galaxies in the early Universe remains uncertain, largely due to the difficulty of directly linking mergers to quenching.
