M. Wittkowski, G. Beccari, A. Corporaal +15
The paper describes recent user‑focused upgrades to the VLTI, including new guiding and instrument modes, enhanced observation‑planning tools, and the availability of reduced GRAVI…
ESOFinder: an LLM-powered tool to help users navigate ESO documentation
P. Sánchez-Sáez, C. Reinero, M. Vioque +6
The large amount and diversity of documentation available for users of the European Southern Observatory (ESO), spanning the full observing lifecycle from proposal preparation and…
Absolute Calibration of Cluster Mira Variables to Provide a New Anchor for the Hubble Constant Determination
Anupam Bhardwaj, Noriyuki Matsunaga, Caroline D. Huang +2
Mira variables in globular clusters can provide an accurate and precise absolute calibration of their period-luminosity relations (PLRs) to independently anchor the cosmic distance…
The VMC Survey -- LIV. Anomalous Cepheids in the Magellanic Clouds Period-Luminosity relations in the near-infrared bands
Teresa Sicignano, Vincenzo Ripepi, Marina Rejkuba +12
Anomalous Cepheids (ACs) are less studied metal-poor pulsating stars ([Fe/H]<-1.5) compared to Classical Cepheids (CCs) and RR Lyrae stars. They follow distinct Period-Luminosity (…
Euclid Quick Data Release (Q1) Ultracool dwarfs in the Euclid Deep Field North
A. Mohandasan, R. L. Smart, C. Reylé +176
Ultracool dwarfs (UCDs) encompass the lowest mass stars and brown dwarfs, defining the stellar substellar boundary. They have significant potential for advancing the understanding…
