EWOCS-IX: JWST/NIRCam observations of Westerlund 2 - Identification of candidate substellar members

V. Almendros-Abad, M. G. Guarcello, K. Muzic +26

[Abridged] Investigating substellar populations in young massive clusters offers crucial insights into the formation of brown dwarfs (BDs) and the role of environmental conditions…

EWOCS-III: JWST observations of the supermassive star cluster Westerlund 1

M. G. Guarcello, V. Almendros-Abad, J. B. Lovell +29

The typically large distances, extinction, and crowding of Galactic supermassive star clusters have so far hampered the identification of their very low mass members, required to e…

On Convective Turnover Times and Dynamos In Low-Mass Stars

Seth Gossage, Rocio Kiman, Kristina Monsch +7

The relationship between magnetic activity and Rossby number is one way through which stellar dynamos can be understood. Using measured rotation rates and X-ray to bolometric lumin…

EWOCS-II: X-ray properties of the Wolf-Rayet stars in the young Galactic super star cluster Westerlund 1

K. Anastasopoulou, M. G. Guarcello, E. Flaccomio +20

We present the most comprehensive and deepest X-ray study to date of the properties of the richest Wolf-Rayet (WR) population observed in a single stellar cluster, Westerlund 1 (Wd…

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Westerlund 1 and 2 Open Clusters Survey

M. G. Guarcello, E. Flaccomio, J. F. Albacete-Colombo +48

Context. With a mass exceeding several 10^4 solar masses and a rich and dense population of massive stars, supermassive young star clusters represent the most massive star-forming…

Classification of Chandra X-ray Sources in Cygnus OB2

Vinay L. Kashyap, Mario G. Guarcello, Nicholas J. Wright +11

We have devised a predominantly Naive Bayes method to classify the optical/IR matches to X-ray sources detected by Chandra in the Cygnus OB2 association into foreground, member, an…
