We present a study correlating the spatial locations of young star clusters with those of molecular clouds in NGC 5194, in order to investigate the time-scale over which clusters separate from their birth clouds. The star cluster catalogues are from... Read More about The spatial relation between young star clusters and molecular clouds in M51 with LEGUS.

In the hierarchical model of structure formation, giant elliptical galaxies form through merging processes within the highest density peaks known as protoclusters. While high-redshift radio galaxies usually pinpoint the location of these environments... Read More about Overdensity of submillimeter galaxies around the z ≃ 2.3 MAMMOTH-1 nebula.

Exploring the origins of a new, apparently metal-free gas cloud at z = 4.4 (2018)
Journal Article

We report the discovery and analysis of only the third Lyman-limit system in which a high-quality resolution, echelle spectrum reveals no metal absorption lines, implying a metallicity ≲1/10 000 solar. Our HIRES spectrum of the background quasar, PSS... Read More about Exploring the origins of a new, apparently metal-free gas cloud at z = 4.4.
