Chemical evolution of star clusters
Jacco Th. van Loon
I discuss the chemical evolution of star clusters, with emphasis on old globular clusters, in relation to their formation histories. Globular clusters clearly formed in a complex f…
Detailed maps of interstellar clouds in front of omega Centauri: Small-scale structures in the Galactic Disc-Halo interface
Jacco Th. van Loon, Keith T. Smith, Iain McDonald +3
We used the multiplex capabilities of the AAOmega spectrograph at the Anglo-Australian Telescope to create a half-square-degree map of the neutral and low-ionized ISM in front of t…
A Suzaku observation of the ULIRG IRAS19254-7245: disclosing the AGN component
V. Braito, J. N. Reeves, R. Della Ceca +3
We discuss here a long Suzaku observation of IRAS 19254-7245 (also known as the Superantennae), one of the brightest and well studied Ultra Luminous Infrared Galaxies in the local…
A Spitzer Study of Asymptotic Giant Branch Stars. III. Dust Production and Gas Return in Local Group Dwarf Irregular Galaxies
Martha L. Boyer, Evan D. Skillman, Jacco Th. van Loon +2
We present the third and final part of a census of Asymptotic Giant Branch (AGB) stars in Local Group dwarf irregular galaxies. Papers I and II presented the results for WLM and IC…
A peculiar HI cloud near the distant globular cluster Pal 4
Jacco Th. van Loon, Snezana Stanimirovic, Mary Putman +4
We present 21-cm observations of four Galactic globular clusters, as part of the on-going GALFA-HI Survey at Arecibo. We discovered a peculiar HI cloud in the vicinity of the dista…
