Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake. How do Planetary Systems Form?
I. MendigutÃa, N. Huélamo, I. Jiménez-Serra +32
The detection and characterization of protoplanets in protoplanetary disks around young stars is emerging as a transformative field that will redefine our understanding of how plan…
Euclid: Quick Data Release (Q1) -- A photometric search for ultracool dwarfs in the Euclid Deep Fields
M. Žerjal, C. Dominguez-Tagle, N. Vitas +178
We present a catalogue of 5306 new ultracool dwarf (UCD) candidates in the three Euclid Deep Fields in the Q1 data release. They range from late M to late T dwarfs, and include 120…
Euclid: The potential of slitless infrared spectroscopy: A z=5.4 quasar and new ultracool dwarfs
E. Bañados, V. Le Brun, S. Belladitta +226
We demonstrate the potential of Euclid's slitless spectroscopy to discover high-redshift (z>5) quasars and their main photometric contaminant, ultracool dwarfs. Sensitive infrared…
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…
