TL;DR: The Infrared Spectrograph (IRS) as discussed by the authors is one of the three science instruments on the Spitzer Space Telescope and is optimized to take full advantage of the very low background in the space environment.

TL;DR: In this article, the Hungarian National Research, Development and Innovation Office (K-119517) and Hungarian National Science Foundation (KNFI) have proposed a method to detect the presence of asteroids in Earth's magnetic field.

TL;DR: The Apache Point Observatory Galactic Evolution Experiment (APOGEE) as discussed by the authors collected a half million high resolution (R~22,500), high S/N (>100), infrared (1.51-1.70 microns) spectra for 146,000 stars, with time series information via repeat visits to most of these stars.

TL;DR: The Apache Point Observatory Galactic Evolution Experiment (APOGEE) as mentioned in this paper uses a dedicated 300-fiber, narrow-band (1.5-1.7 micron) near-infrared spectrograph to survey approximately 100,000 giant stars across the Milky Way.

TL;DR: In this article, an ensemble of microlensing events from the 2015 Spitzer micro-lensing campaign, all of which were densely monitored by ground-based high-cadence survey teams, were analyzed and the planet sensitivities of all 41 events in the sample were calculated, from which compact constraints on the microlens properties were derived, including the uncertainties on the lens mass and distance.
