Nitrogen lines of the N I lambda1134 and lambda1200 multiplets in the damped Lyalpha (DLA) galaxies at z_abs = 2.309, 2.827, and 3.025 toward the QSOs 0100+1300...
NLTE Analysis of High-Resolution H-band Spectra. I. Neutral Silicon
We investigated the reliability of our silicon atomic model and the influence of non-local thermodynamical equilibrium (NLTE) on the formation of neutral...
NLTE Analysis of High-resolution H-band Spectra. II. Neutral Magnesium
Aiming at testing the validity of our magnesium atomic model and investigating the effects of non-local thermodynamical equilibrium (NLTE) on the formation of...
No Evidence for a Dependence of the Mass-Size Relation of Early-type Galaxies on Environment in the Local Universe
The early-type galaxy (ETG) mass-size relation has largely been studied to understand how these galaxies assembled their mass. One key observational result of...
No Evidence for Critical Balance in Field-aligned Alfvénic Solar Wind Turbulence
The properties of Alfvénic solar wind turbulence have been studied for decades using spacecraft measurements. In particular, the observation of spectral...
We have surveyed Kepler’s supernova remnant in search of the companion star of the explosion. We have gone as deep as 2.6 L ⊙ in all stars within 20% of the...
Non-detection of He I in the Atmosphere of GJ 1214b with Keck/NIRSPEC, at a Time of Minimal Telluric Contamination
Observations of helium in exoplanet atmospheres may reveal the presence of large gaseous envelopes and indicate ongoing atmospheric escape. Orell-Miquel et al....
Non-LTE Determination of the Silicon Abundance Using a Three-dimensional Hydrodynamical Model of the Solar Photosphere
Confrontations of spectroscopic observations with local thermodynamic equilibrium (LTE) spectral syntheses in a three-dimensional (3D) hydrodynamical model of...
