A no-moving-part planar array infrared spectrograph (PA-IR) equipped with a 256 x 256 mercury cadmium telluride (MCT) focal plane array has been designed and constructed. The performance of the instrument, whose frequency range extends from 2000-975 cm(-1), has been assessed in terms of resolution, bandwidth, and signal-to-noise ratio. The PA-IR spectrograph is able to record spectra with an 8....
We report on a large survey for double degenerate (DD) binaries as potential progenitors of type Ia supernovae with the UVES spectrograph at the ESO VLT (ESO SN Ia Progenitor surveY – SPY).
We present the Deep Integral Field Spectrograph View of Nuclei Galaxies (DIVING$^{3D}$) survey, a seeing-limited optical 3D spectroscopy study central regions all 170 galaxies in Southern hemisphere with B < 12.0 and |b| > 15 degrees. Most observations were taken Unit Gemini Multi-Object Spectrograph, at South telescope, but some are also being Astrophysical Research Telescope (SOAR) Spectrogra...
Abstract The Extreme-ultraviolet Snapshot Imaging Spectrograph (ESIS) launched on a sounding rocket from White Sands Missile Range 2019 September 30. ESIS is computed tomography imaging spectrograph (CTIS) designed to map emission line profiles across wide field of view, revealing the structure and dynamics small-scale transient events that are prevalent at transition region temperatures. In th...
