On the origin of UV-dim stars: a population of rapidly rotating shell stars?
Silvia Martocchia, Nate Bastian, Sara Saracino +1
The importance of stellar rotation in setting the observed properties of young star clusters has become clearer over the past decade, with rotation being identified as the main cau…
Expanding the time domain of multiple populations: evidences of nitrogen variations in the ~1.5 Gyr old star cluster NGC 1783
M. Cadelano, E. Dalessandro, M. Salaris +5
We present the result of a detailed analysis of HST UV and optical deep images of the massive and young (~1.5 Gyr) stellar cluster NGC 1783 in the Large Magellanic Cloud. This syst…
The WAGGS project -- III. Discrepant mass-to-light ratios of Galactic globular clusters at high metallicity
H. Dalgleish, S. Kamann, C. Usher +10
Observed mass-to-light ratios (M/L) of metal-rich globular clusters (GCs) disagree with theoretical predictions. This discrepancy is of fundamental importance since stellar populat…
The WISSH Quasars Project III. X-ray properties of hyper-luminous quasars
S. Martocchia, E. Piconcelli, L. Zappacosta +14
We perform a survey of the X-ray properties of 41 objects from the WISE/SDSS selected Hyper-luminous (WISSH) quasars sample, composed by 86 broad-line quasars (QSOs) with bolometri…
The WISSH Quasars Project I. Powerful ionised outflows in hyper-luminous quasars
M. Bischetti, E. Piconcelli, G. Vietri +19
Models and observations suggest that both power and effects of AGN feedback should be maximised in hyper-luminous (L_Bol>10^47 erg/s) quasars, i.e. objects at the brightest end of…
