The Search for Stable Nickel: Investigating the Origins of Type Ia Supernovae with Late-time Near-infrared Spectroscopy from the Carnegie Supernova Project-II

The Astrophysical Journal
Producing stable ^58 Ni in Type Ia supernovae (SNe Ia) requires sufficiently high-density conditions that are not predicted for all origin scenarios, so examining the distribution of ^58 Ni using the near-infrared (NIR) [Ni II ] 1.939 μ m line may ...

Antarctic Infrared Binocular Telescope: Early Data Release of Observations in the 1.4 μm Water-vapor-absorption Band

The Astronomical Journal
Ground-based observations around 1.4 μ m are normally limited by strong absorption of telluric water-vapor. However, Dome A, Antarctica has exceptionally dry conditions that offer a unique opportunity for observations in this band.

Science Impacts of the SPHEREx All-Sky Optical to Near-Infrared Spectral Survey II: Report of a Community Workshop on the Scientific Synergies Between the SPHEREx Survey and Other Astronomy Observatories [PDF]

, 2018
SPHEREx is a proposed NASA MIDEX mission selected for Phase A study. SPHEREx would carry out the first all-sky spectral survey in the near infrared. At the end of its two-year mission, SPHEREx would obtain 0.75-to-5$ $m spectra of every 6.2 arcsec pixel on the sky, with spectral resolution R>35 and a 5-$ $ sensitivity AB$>$19 per spectral ...

First Daytime Near-infrared Photometric Observations at Antarctic Dome A

The Astronomical Journal
Located at the highest point on the Antarctic Plateau’s ice sheet, Dome A is generally believed to be one of the best places on Earth for nighttime astronomy in the optical and near-infrared (NIR) bands.

Looking at Infrared Background Radiation Anisotropies with Spitzer: Large-scale Anisotropies and Their Implications

The Astrophysical Journal Letters
We use Spitzer/IRAC deep-exposure data covering two significantly larger than before sky areas to construct maps suitable for evaluating source-subtracted fluctuations in the cosmic infrared background (CIB).

COSMOS-Web: Comprehensive Data Reduction for Wide-area JWST NIRCam Imaging

The Astrophysical Journal
We present the data reduction methodology used for the COSMOS-Web survey JWST NIRCam data. Covering 0.54 deg ^2 with four broadband filters (F115W, F150W, F277W, F444W) and a total exposure time of approximately 270 hr, COSMOS-Web represents the largest ...

A Cometary Fluorescence Model for the ν3 Vibrational Band of Cyanogen

The Astrophysical Journal
Cyanogen (C _2 N _2 ) has been suspected for a long time to be present in comets and to contribute to the creation of the CN radical. So far no observations with ground-based facilities have managed to detect this species, but the Rosetta mission, thanks
