New long-slit optical spectroscopy and optical and NIR images of NGC 520 are presented. Velocity-dispersion and radial-velocity profiles are obtained from the...
The Large Scale IMF-from local studies to large scale Star-formation
Over the past years observations of young and populous star clusters have shown that the stellar IMF appears to be an invariant featureless Salpeter power-law...
The Lazy Giants: APOGEE Abundances Reveal Low Star Formation Efficiencies in the Magellanic Clouds
We report the first APOGEE metallicities and α-element abundances measured for 3600 red giant stars spanning a large radial range of both the Large (LMC) and...
The Main Sequence at z ∼ 1.3 Contains a Sizable Fraction of Galaxies with Compact Star Formation Sizes: A New Population of Early Post-starbursts?
Atacama Large Millimeter/submillimeter Array (ALMA) measurements for 93 Herschel-selected galaxies at 1.1 ≤ z ≤ 1.7 in COSMOS reveal a sizable (>29%) population...
The mean star formation rate of X-ray selected active galaxies and its evolution from z ~ 2.5: results from PEP-Herschel
We study relationships between star-formation rate (SFR) and the accretion luminosity and nuclear obscuration of X-ray selected active galactic nuclei (AGNs)...
The Mg/Fe characterisation of MILES library for stellar population
The current databases of empirical star spectra for modelling single-aged stellar populations (SSPs) generally do not chemically characterize their stars...
The morphologies and masses of extremely red galaxies in the Groth Strip
We present a new catalogue of EROs from the Groth Strip and study the relation between their morphology and mass. With a selection criterion F814W-Ks≥ 4 and Ks≤...
The multifarious ionization sources and disturbed kinematics of extraplanar gas in five low-mass galaxies
Aims: We investigate the origin of the extraplanar diffuse ionized gas (eDIG) and its predominant ionization mechanisms in five nearby (17-46 Mpc) low-mass (10...
The MUSE Atlas of Disks (MAD): resolving star formation rates and gas metallicities on <100 pc scales†
We study the physical properties of the ionized gas in local discs using the sample of 38 nearby ˜108.5-11.2 M⊙ Star-Forming Main-Sequence (SFMS) galaxies...
