Entropic crystallization of geometrically frustrated magnets on 1/1 approximant Tsai-type quasicrystal
Oscar Novat, Ludovic D. C. Jaubert, Masafumi Udagawa
We have studied the antiferromagnetic Ising model on the icosahedral bcc lattice, as a model system of 1/1 approximant Tsai-type quasicrystals. We addressed thermal equilibrium pro…
Euclid: Early Release Observations -- The star-formation history of massive early-type galaxies in the Perseus cluster
S. Martocchia, A. Boselli, J. -C. Cuillandre +157
The Euclid Early Release Observations (ERO) programme targeted the Perseus galaxy cluster in its central region over 0.7deg. We combined the exceptional image quality and depth…
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: Early Release Observations of diffuse stellar structures and globular clusters as probes of the mass assembly of galaxies in the Dorado group
M. Urbano, P. -A. Duc, T. Saifollahi +160
Deep surveys reveal tidal debris and associated compact stellar systems. Euclid's unique combination of capabilities (spatial resolution, depth, and wide sky coverage) will make it…
Temperature dependent Resonant X-ray Inelastic Scattering at Ni L3-edge for NaNiO2 and LiNiO2
Quentin Jacquet, Kurt Kummer, Marie Guignard +4
LiNiO2 is a promising cathode material for Li-ion battery but its atomic and electronic structure is under debate. Indeed, two sets of Ni-O distances are identified from local stru…
SCOTCH III: Complete search for Hypercompact HII regions in the fourth quadrant
A. L. Patel, J. S. Urquhart, A. Y. Yang +7
We present high-frequency (18-24 GHz) radio continuum observations towards 335 methanol masers, excellent signposts for young, embedded high-mass protostars. These complete the sea…
