Expanding stellar associations as Galactic accelerometers

Till Sawala, Núria Miret Roig

The gravitational potential of the Milky Way is fundamental for understanding the evolution of our Galaxy and the nature of dark matter. We introduce a new method to constrain the…

When Two Worlds Collide: How Collisions Between Silicate and Carbonaceous Nanograins can Drive Complex Chemistry

Alexandros Kyriazis, Albert Rimola, Stefan T. Bromley

Our overall objective is to determine how collision velocity governs the interactions between silicate and carbonaceous nanograins. We aim to: i) identify collisional regimes capab…

Discovery of an Unbound Flyby Companion of UBC 63: In the Immediate Aftermath of a Close Encounter

Samrat Biswas, Biman J Medhi, Sergio Messina +8

We re-investigate the open cluster UBC 63 using the Gaia DR3 data and show that, rather than being a single cluster as previously classified, it is a compelling candidate for a dou…

Detection of C Combination Bands in the Near-IR Spectrum of Tc 1

Morgan M. Giese, Vincent J. Esposito, Simon Van Schuylenbergh +26

We report the detection of a set of new near-infrared emission features between 3.5 and 5.2 m in JWST/NIRSpec observations of Tc 1, the planetary nebula known for displaying the…

Chemo-dynamical reconstruction of Milky Way globular cluster progenitors: Age-metallicity relations and the universality of multiple stellar populations

Carmela Lardo, David Valcin, Raul Jimenez

Globular clusters encode the hierarchical assembly history of the Milky Way and the physics of multiple stellar populations. Using homogeneous stellar parameters for 69 Galactic gl…

Random gas motions inside sub-parsec scale supercritical filaments

Chao Zhang, Tie Liu, Mika Juvela +12

Supercritical gas filaments in molecular clouds host the dense cores in which new stars form. The mechanisms governing their formation and subsequent gas accretion remain poorly un…
