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 Fields
A. Mohandasan, R. L. Smart, C. Reylé +180
Ultracool dwarfs (UCDs) encompass the lowest-mass stars and brown dwarfs at the substellar boundary. These intrinsically faint objects are challenging to detect, but the wide cover…
CaII and H flaring M dwarfs detected with multi-filter photometry
P. Mas-Buitrago, J. -Y. Zhang, E. Solano +1
Understanding and characterising the magnetic activity of M dwarfs is of paramount importance in the search for Earth-like exoplanets orbiting them. Energetic stellar activity phen…
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 Quick Data Release (Q1) -- Spectroscopic search, classification and analysis of ultracool dwarfs in the Deep Fields
C. Dominguez-Tagle, M. Žerjal, N. Sedighi +14
The Near-Infrared Spectrometer and Photometer onboard the Euclid space mission has obtained near-infrared (NIR) slitless spectra of millions of objects, including hundreds of ultra…
The wide binary frequency of metal-poor stars
N. Lodieu, A. Pérez Garrido, J. -Y. Zhang +5
This study is aimed at identifying possible low-mass and sub-stellar companions to stars with well-determined metallicities. We investigate the multiplicity of metal-poor stars alo…
