What is driving the evolution of the far-infrared radio correlation? [PDF]
Zbornik Matice Srpske za Prirodne Nauke, 2019 Far infrared-radio correlation represents a linear relationship between far-infrared (FIR) and radio emission in star-forming galaxies. Previous observations have confirmed that this correlation is maintained over a large range of redshift and ...

Abundance diagnosis of E+A (post-starburst) galaxies [PDF]
Mon.Not.Roy.Astron.Soc.377:1222-1228,2007, 2007 E+A galaxies are characterized as a galaxy with strong Balmer absorption lines but without any [OII] or H$\alpha$ emission lines. The existence of strong Balmer absorption lines means that E+A galaxies have experienced a starburst within the last $<$1-1.5 gigayear.

Searching the Non‐Accreting White Dwarf Population in eROSITA Data
Astronomische Nachrichten, Volume 346, Issue 1, January 2025.ABSTRACT eROSITA is the soft X‐ray instrument aboard the Spectrum Roentgen Gamma (SRG) satellite that is most sensitive in the energy range between 0.2 and 2.3 keV. Between December 2019 and December 2021, eROSITA completed four all‐sky surveys, producing all‐sky X‐ray source lists and sky maps of unprecedented depth.

Chiral Emission from Optical Metasurfaces and Metacavities
Advanced Photonics Research, Volume 5, Issue 12, December 2024.Chiral emission with near‐unity degree of circular polarization and strong emission intensities is highly desirable. This review discusses recent experimental demonstrations on chiral emission from achiral emitters that are combined with patterned nanostructures.

The Astrophysical Journal Letters, 2023 Ly α emission is possibly the best indirect diagnostic of Lyman continuum (LyC) escape since the conditions that favor the escape of Ly α photons are often the same that allow for the escape of LyC photons.

Advanced Physics Research, Volume 3, Issue 11, November 2024.This study explores Brownian motion in enhanced green fluorescent protein (EGFP) using luminescence nanothermometry. How protein concentration and temperature impact EGFP dynamics is demonstrated providing insights into protein behavior in crowded environments.

The Astrophysical JournalRecent observations and theories have presented a strong challenge to the universality of the stellar initial mass function (IMF) in extreme environments. A notable example has been found for starburst conditions, where evidence favors a top-heavy IMF, i.
