Wide-field dynamic astronomy in the near-infrared with Palomar Gattini-IR and DREAMS [PDF]
Advances in Optical Astronomical Instrumentation 2019, 2020 There have been a dramatic increase in the number of optical and radio transient surveys due to astronomical transients such as gravitational waves and gamma ray bursts, however, there have been a limited number of wide-field infrared surveys due to narrow field-of-view and high cost of infrared cameras, we present two new wide-field near-infrared ...

Optimizing photonic ring-resonator filters for OH-suppressed near-infrared astronomy
Applied Optics, 2021 Near-infrared wavelength observations are crucial for understanding numerous fields of astrophysics, such as supernova cosmology and positronium annihilation detection. However, current ground-based observations suffer from an enormous background due to OH emission in the upper atmosphere.

Integration of a Testbench for the Optical and Thermal Characterization of Near-Infrared Detectors Used in Ground and Space-Based Astronomy [PDF]
IEEE Transactions on Instrumentation and Measurement, 2021 The mercury–cadmium–tellurium (MCT) sensors are considered the ideal infrared detectors to equip the focal plane arrays (FPAs) of astronomical scientific missions. To tackle Europe to be self-sufficient on this technology and promote to reach the same maturity level attained by the current MCT sensors market leaders, the Astronomy European Infrared ...

First tests of a 1 megapixel near-infrared avalanche photodiode array for ultra-low background space astronomy [PDF]
X-Ray, Optical, and Infrared Detectors for Astronomy X, 2022 Spectroscopy of Earth-like exoplanets and ultra-faint galaxies are priority science cases for the coming decades. Here, broadband source flux rates are measured in photons per square meter per hour, imposing extreme demands on detector performance, including dark currents lower than 1 e-/pixel/kilosecond, read noise less than 1 e-/pixel/frame, and ...

Background-limited Imaging in the Near Infrared with Warm InGaAs Sensors: Applications for Time-domain Astronomy [PDF]
The Astronomical Journal, 2019 Abstract We describe test observations made with a customized 640 × 512 pixel indium gallium arsenide (InGaAs) prototype astronomical camera on the 2.5 m DuPont telescope. This is the first test of InGaAs as a cost-effective alternative to HgCdTe for research-grade astronomical observations. The camera exhibits a background of 113 e– s–1/

Design of microstrip-line coupled kinetic inductance detectors for near infrared astronomy
Millimeter, Submillimeter, and Far-Infrared Detectors and Instrumentation for Astronomy XI, 2022 Kinetic inductance detectors (KID) have great potential in astronomical observation, such as searching for exoplanets, because of their low noise, fast response and photon counting characteristics. In this paper, we present the design process and simulation results of a microstrip line coupled KIDs array for near-infrared astronomical observation ...
