Star cluster formation in the most extreme environments: Insights from the HiPEEC survey
A. Adamo, K. Hollyhead, M. Messa +14
We present the Hubble imaging Probe of Extreme Environments and Clusters (HiPEEC) survey. We fit HST NUV to NIR broadband and H fluxes, to derive star cluster ages, masses, exti…
Spectroscopic detection of multiple populations in the ~2 Gyr old cluster Hodge 6 in the LMC
K. Hollyhead, S. Martocchia, C. Lardo +8
We report the spectroscopic discovery of abundance spreads (i.e. multiple populations) in the ~2 Gyr old cluster in the LMC, Hodge 6. We use low resolution VLT FORS2 spectra of 15…
Kron 3: a fourth intermediate age cluster in the SMC with evidence of multiple populations
K. Hollyhead, C. Lardo, N. Kacharov +6
We present the results of a spectroscopic study of the intermediate age (approximately 6.5 Gyr) massive cluster Kron 3 in the Small Magellanic Cloud. We measure CN and CH band stre…
Interpreting the complex CMDs of the Magellanic Clouds clusters
I. Cabrera-Ziri, S. Martocchia, K. Hollyhead +1
The Magellanic Clouds host a large population of massive (> 10^4 Msun) star clusters with ages ranging from a few Myr to 12 Gyr. In nearly all cases, close inspection of their CMDs…
Age as a Major Factor in the Onset of Multiple Populations in Stellar Clusters
S. Martocchia, I. Cabrera-Ziri, C. Lardo +16
It is now well established that globular clusters (GCs) exhibit star-to-star light-element abundance variations (known as multiple stellar populations, MPs). Such chemical anomalie…
The Search for Multiple Populations in Magellanic Cloud Clusters III: No evidence for Multiple Populations in the SMC cluster NGC 419
S. Martocchia, N. Bastian, C. Usher +16
We present the third paper about our ongoing HST survey for the search for multiple stellar populations (MPs) within Magellanic Cloud clusters. We report here the analysis of NGC 4…
Evidence for multiple populations in the intermediate age cluster Lindsay 1 in the SMC
K Hollyhead, N Kacharov, C Lardo +6
Lindsay 1 is an intermediate age (approx 8 Gyr) massive cluster in the Small Magellanic Cloud (SMC). Using VLT FORS2 spectra of 16 probable cluster members on the lower RGB of the…
Sizes and Shapes of Young Star Cluster Light Profiles in M83
Jenna E. Ryon, Nate Bastian, Angela Adamo +6
We measure the radii and two-dimensional light profiles of a large sample of young, massive star clusters in M83 using archival HST/WFC3 imaging of seven adjacent fields. We use GA…
Studying the YMC population of M83: how long clusters remain embedded, their interaction with the ISM and implications for GC formation theories
Katherine Hollyhead, Nate Bastian, Angela Adamo +4
The study of young massive clusters can provide key information for the formation of globular clusters, as they are often considered analogues. A currently unanswered question in t…
Constraining globular cluster formation through studies of young massive clusters - V. ALMA observations of clusters in the Antennae
I. Cabrera-Ziri, N. Bastian, S. N. Longmore +9
Some formation scenarios that have been put forward to explain multiple populations within Globular Clusters (GCs) require that the young massive cluster have large reservoirs of c…
Constraining Globular Cluster Formation Through Studies of Young Massive Clusters - IV. Testing the Fast Rotating Massive Star Scenario
Nate Bastian, Katie Hollyhead, Ivan Cabrera-Ziri
One of the leading models for the formation of multiple stellar populations within globular clusters is the "Fast Rotating Massive Star" (FRMS) scenario, where the ejecta of rapidl…
The effect of spatial resolution on optical and near-IR studies of stellar clusters: Implications for the origin of the red excess
N. Bastian, A. Adamo, M. Schirmer +6
Recent ground based near-IR studies of stellar clusters in nearby galaxies have suggested that young clusters remain embedded for 7-10Myr in their progenitor molecular cloud, in co…
