Charting the Galactic acceleration field II. A global mass model of the Milky Way from the STREAMFINDER Atlas of Stellar Streams detected in Gaia DR3
Rodrigo Ibata, Khyati Malhan, Wassim Tenachi +17
We present an atlas and follow-up spectroscopic observations of 87 thin stream-like structures detected with the STREAMFINDER algorithm in Gaia DR3, of which 29 are new discoveries…
Bars and boxy/peanut bulges in thin and thick discs III. Boxy/peanut bulge formation and evolution in presence of thick discs
Soumavo Ghosh, Francesca Fragkoudi, Paola Di Matteo +1
Boxy/peanut (b/p) bulges, the vertically extended inner parts of bars, are ubiquitous in barred galaxies in the local Universe, including our own Milky Way. At the same time, a maj…
Looking for a needle in a haystack: Measuring the length of a stellar bar
Soumavo Ghosh, Paola Di Matteo
One of the challenges related to stellar bars is to accurately determine the length of the bar in a disc galaxy. In the literature, a wide variety of methods have been employed to…
Stragglers of the thick disc
Valeria Cerqui, Misha Haywood, Paola Di Matteo +2
Young alpha-rich (YAR) stars have been detected in the past as outliers to the local age [/Fe] relation. These objects are enhanced in -elements but apparently younger…
The e-TidalGCs Project: Modeling the extra-tidal features generated by Galactic globular clusters
Salvatore Ferrone, Paola Di Matteo, Alessandra Mastrobuono-Battisti +5
We present the e-TidalGCs Project which aims at modeling and predicting the extra-tidal features surrounding all Galactic globular clusters for which 6D phase space information, ma…
