Hidden Gems on a Ring: Infant Massive Clusters and Their Formation Timeline Unveiled by ALMA, HST, and JWST in NGC 3351
Robin Gopala Tress, Jiayi Sun, Hamid Hassani, Hao He
We use 0.1 '' observations from the Atacama Large Millimeter Array (ALMA), Hubble Space Telescope (HST), and JWST to study young massive clusters (YMCs) in their embedded "infant" phase across the central starburst ring in NGC 3351. Our new ALMA data revea ...
Iop Publishing Ltd2024Characterization of Transverse Instabilities Driven by Electron Cloud
Electron cloud continues to be one of the main limiting factors of the Large Hadron Collider (LHC), the biggest accelerator at CERN. These clouds form in the beam chamber when positively charged particles are passing through and cause unwanted effects in b ...
EPFL2024The Pristine survey - XVI. The metallicity of 26 stellar streams around the Milky Way detected with the STREAMFINDER in Gaia EDR3
Pascale Jablonka, Carmela Lardo
We use the photometric metallicities provided by the panoramic Pristine survey to study the veracity and derive the metallicities of the numerous stellar streams found by the application of the STREAMFINDER algorithm to the Gaia Early Data Release 3 data. ...
OXFORD UNIV PRESS2022Halo Mass-concentration Relation at the High-mass End
Jean-Paul Richard Kneib, Huanyuan Shan, Ginevra Favole
The concentration-mass (c-M) relation encodes key information about the assembly history of dark matter halos. However, its behavior at the high mass end has not been measured precisely in observations yet. In this paper, we report the measurement of the h ...
IOP Publishing Ltd2021Multiple Stellar Populations in Globular Clusters
Globular clusters (GCs) exhibit star-to-star variations in specific elements (e.g., He, C, N, O, Na, Al) that bear the hallmark of high-temperature H-burning. These abundance variations can be observed spectroscopically and also photometrically, with the a ...
ANNUAL REVIEWS2018The Gaia-ESO Survey: dynamics of ionized and neutral gas in the Lagoon nebula (M 8)
Aims. We present a spectroscopic study of the dynamics of the ionized and neutral gas throughout the Lagoon nebula (M 8), using VLT-FLAMES data from the Gaia-ESO Survey. The new data permit exploration of the physical connections between the nebular gas an ...
Edp Sciences S A2017Gaia Data Release 1 Open cluster astrometry: performance, limitations, and future prospects
Stephan Morgenthaler, Mikaël Martino, Shuangqing Liao
Context. The first Gaia Data Release contains the Tycho-Gaia Astrometric Solution (TGAS). This is a subset of about 2 million stars for which, besides the position and photometry, the proper motion and parallax are calculated using Hipparcos and Tycho-2 po ...
