PublicationYoung Stellar Populations and Star Clusters in NGC 1705
We present Hubble Space Telescope (HST) photometry of the late-type dwarf galaxy NGC 1705 observed with the Wide-Field Planetary Camera 2 (WFPC2) in the F380W...

PublicationYoung stellar populations in type II quasars: timing the onset of star formation and nuclear activity
Despite the emerging morphological evidence that luminous quasar-like active galactic nuclei (AGN) are triggered in galaxy mergers, the natures of the...

PublicationYoung Super Star Clusters in the Starburst of M82: The Catalog
Recent results from the Hubble Space Telescope (HST) have resolved starbursts as collections of compact young stellar clusters. Here we present a photometric...

PublicationYoung T-dwarf candidates in IC 348
Context: The determination of the lower-end of the initial mass function (IMF) provides strong constraints on star formation theories. Aims: We report here on a...

PublicationYoung [α/Fe]-enhanced stars discovered by CoRoT and APOGEE: What is their origin?
We report the discovery of a group of apparently young CoRoT red-giant stars exhibiting enhanced [α/Fe] abundance ratios (as determined from APOGEE spectra)...

PublicationYoung α-enriched giant stars in the solar neighbourhood
We derive age constraints for 1639 red giants in the APOKASC sample for which seismic parameters from Kepler, as well as effective temperatures, metallicities...

PublicationYoung, Blue, and Isolated Stellar Systems in the Virgo Cluster. I. 2D Optical Spectroscopy
We use panoramic optical spectroscopy obtained with the Very Large Telescope/MUSE to investigate the nature of five candidate extremely isolated low-mass star...
