Self-Interacting Dark Matter in Brown Dwarfs

A. Pérez-Garrido

Brown dwarfs, being transitional objects between giant planets and low-mass stars, possess dense, cool interiors that provide optimal conditions to explore non-standard physics. Ca…

Scattering matrix elements and energy spectrum of one-dimensional hybrid PT-symmetric finite systems

Vladimir Gasparian, Esther Jódar, Antonio Pérez-Garrido

In this work, we provide a complete description of the scattering matrix elements and electron energy spectrum in one dimensional PT-symmetric hybrid finite systems, using the char…

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…

Euclid: Early Release Observations -- A glance at free-floating new-born planets in the sigma Orionis cluster

E. L. Martín, M. {Ž}erjal, H. Bouy +175

We provide an early assessment of the imaging capabilities of the Euclid space mission to probe deeply into nearby star-forming regions and associated very young open clusters, and…
