This is a proposal for 98 hours of NIRSPEC/PRISM observations of 59 trans-Neptunian objects and Centaurs (hereafter, TNOs). Our targets cover a diverse range of orbital characteristics, sizes, albedos, and surface compositions complementary to the GTO targets. The TNO population includes some of the most primitive bodies in the Solar System and

BOSS-EUVLG1 is the most ultraviolet (UV) and Lyα luminous galaxy to be going through a very active starburst phase detected thus far in the Universe. It is forming stars at a rate of 955 ± 118 M ⊙ yr ‒1. We report the detection of a broad Hα component carrying 25% of the total Hα flux. The broad Hα line traces a fast and massive ionized gas outflow

Upcoming large-area narrow band photometric surveys, such as Javalambre Physics of the Accelerating Universe Astrophysical Survey (J-PAS), will enable us to observe a large number of galaxies simultaneously and efficiently. However, it will be challenging to analyse the spatially resolved stellar populations of galaxies from such big data to

Context. Inversion techniques applied to the radiative transfer equation for polarized light are capable of inferring the physical parameters in the solar atmosphere (temperature T, magnetic field B, and line-of-sight velocity v los) from observations of the Stokes vector (i.e., spectropolarimetric observations) in spectral lines. Inferences are

We study the carbon monoxide (CO) excitation, mean molecular gas density, and interstellar radiation field (ISRF) intensity in a comprehensive sample of 76 galaxies from local to high redshift (z ∼ 0-6), selected based on detections of their CO transitions J = 2 → 1 and 5 → 4 and their optical/infrared/(sub)millimeter spectral energy distributions

Supermassive black holes, and the outflows they drive, are an established part of our understanding of galaxy evolution. Indeed, cosmological models rely on outflows to reproduce the observed scaling relations. But the enormous range of outflow rates that are measured for AGN of the same luminosity, highlights a gaping hole in our understanding of
