Mapping of infrared helium and hydrogen line profiles in the central few arcseconds of the Galaxy
TL;DR: Spectra of the helium 2.06micron and hydrogen 2.17-micron lines, obtained on a grid of positions in the Sgr A-asterisk/IRS 16 region of the Galactic center, confirm the existence of an extended region of high-velocity redshifted line emission centered near these objects as mentioned in this paper.
The velocity profile of the 1 – 0 S(1) line of molecular hydrogen at Peak 1 in Orion
TL;DR: Le profil de vitesse de la raie 1-0 S(1) de l'hydrogene moleculaire mesure dans la region Peak 1 du nuage Moleculaire d'Orion est presente et les explications possibles de ce profil sont analysees as mentioned in this paper.
The Onset of Methane in L Dwarfs
TL;DR: In this paper, weak absorption features produced by the strong ν3 methane band at 3.3 μm were detected in two L dwarfs, 2MASSW J1507476-162738 and 2 MASSI J0825196+211552, classified as spectral types L5 and L7.

TL;DR: In this article, the authors report the discovery of three cool brown dwarfs that fall in the effective temperature gap between the latest L dwarfs currently known, with no methane absorption bands in the 1-2.5 µm range, and the previously known methane (T) dwarfs, whose spectra are dominated by methane and water.
The Giant Herbig-Haro Flow HH 212 and Associated Star Formation

TL;DR: In this article, the bipolar jet HH 212 has been detected only in near-infrared H$_2$ emission, where two major bow shocks are weakly detected in optical [SII] emission, as expected for a bona fide Herbig-Haro jet.
