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…
The magnetic field in quiescent star-forming filament G16.96+0.27
Qi-Lao Gu, Tie Liu, Zhi-Qiang Shen +20
We present 850 μm thermal dust polarization observations with a resolution of 14.4"(~ 0.13 pc) towards an infrared dark cloud G16.96+0.27 using JCMT/POL-2. The average magnetic fie…
The Gaia Ultracool Dwarf Sample -- IV. GTC/OSIRIS optical spectra of Gaia late-M and L dwarfs
W. J. Cooper, H. R. A. Jones, R. L. Smart +20
As part of our comprehensive, ongoing characterisation of the low-mass end of the main sequence in the Solar neighbourhood, we used the OSIRIS instrument at the 10.4 m Gran Telesco…
Quantum Gravity and Cosmology
Houri Ziaeepour
We highlight the structure and properties of an abstract approach to quantum cosmology and gravity, dubbed -QGR. Beginning from the concept of the Universe as an isolat…
Near-infrared spectroscopic characterisation of Gaia ultra-cool dwarf candidates; Spectral types and peculiarities
T. Ravinet, C. Reylé, N. Lagarde +10
Context: The local census of very low-mass stars and brown dwarfs is crucial to improving our understanding of the stellar-substellar transition and their formation history. These…
Exploring the centre of mass properties of LG-like galaxies
Jean-Baptiste Salomon, Noam Libeskind, Yehuda Hoffman
From high resolution cosmological simulations of the Local Group in realistic environment, namely HESTIA simulations, we study the position and kinematic deviations that may arise…
