Hidden Trigger for the Giant Starburst Arc in M83?
The huge star formation events that occur at some galactic centers do not provide enough clues as to their origin, since the morphological signatures of the...
HIDEEP was carried out in a region of Centaurus centred on RA=13h40m00s, DE=30{deg}00'00" (J2000) with 1024 spectral channels covering 1280 to 12700km/s. As a...
Hierarchical Bayesian approach for estimating physical properties in nearby galaxies: Age Maps (Paper II)
One of the fundamental goals of modern astrophysics is to estimate the physical parameters of galaxies. We present a hierarchical Bayesian model to compute age...
Hierarchical star formation across the ring galaxy NGC 6503
We present a detailed clustering analysis of the young stellar population across the star-forming ring galaxy NGC 6503, based on the deep Hubble Space Telescope...
High and low Sérsic index bulges in Milky Way- and M31-like galaxies: origin and connection to the bar with TNG50
We study bulge formation in MW/M31-like galaxies in a Λ-cold dark matter scenario, focusing on the origin of high- and low-Sersic index bulges. For this purpose...
High Dense Gas Fraction in a Gas-rich Star-forming Galaxy at z = 1.2
We report observations of dense molecular gas in the star-forming galaxy EGS 13004291 (z = 1.197) using the Plateau de Bure Interferometer. We tentatively...
High Dense Gas Fraction in Intensely Star-forming Dusty Galaxies
We present ALMA J=3{--}2 and VLA J=1{--}0 observations of the dense molecular gas tracers HCN, HCO+, and HNC in two lensed, high-redshift starbursts selected...
High Frequency Peaker (HFP) radio sources are an extreme class of active galactic nuclei whose nature has not been fully understood yet. They are compact...
We present a sample of sources with convex radio spectra peaking at frequencies above a few GHz, known as ``High Frequency Peakers" (HFPs). A ``bright" sample...
