Astrometric and Photometric Standard Candidates for the Upcoming 4-m International Liquid Mirror Telescope Survey
Kumar, Brajesh; Surdej, Jean; Negi, Vibhore +5 more
The International Liquid Mirror Telescope (ILMT) is a 4-m class survey telescope that has recently achieved first light and is expected to swing into full operations by January 1, 2023. It scans the sky in a fixed 22′ wide strip centered at the declination of 29∘21′41′′ and works in Time Delay Integration (TDI) mode. We present a full catalog of s…
Radiometric Calibration of the Rosetta Navigation Camera
Statella, Thiago; Andrés, Rafael; Geiger, Bernhard
The Navigation Camera (NavCam) on board the Rosetta spacecraft was essential for optical navigation in the vicinity of the comet 67P/Churyumov-Gerasimenko. Images acquired throughout the mission are also of high scientific interest. In order to extend the range of potential applications, we generated datasets of radiometrically calibrated images. …
Conceptual Remote Distance Measurement with a Double-Slit Interference
Zou, Yuan-Chuan
Distance measurement is crucial to astronomy. Here, we suggest a new conceptual method to measure the distance by using a local instrument. By engaging the double-slit interference and by considering the phase information of the light, the position of the intensity maximum is related to the distance of the source. Consequently, the precise measure…
Observing Exoplanets in the Near-Infrared from a High Altitude Balloon Platform
Parmentier, Vivien; Lewis, Nikole K.; Pascale, Enzo +8 more
Although there exists a large sample of known exoplanets, little data exists that can be used to study their global atmospheric properties. This deficiency can be addressed by performing phase-resolved spectroscopy — continuous spectroscopic observations of a planet’s entire orbit about its host star — of transiting exoplanets. Planets with charac…
The SLICE, CHESS, and SISTINE Ultraviolet Spectrographs: Rocket-Borne Instrumentation Supporting Future Astrophysics Missions
France, Kevin; Hoadley, Keri; Nell, Nicholas +4 more
NASA’s suborbital program provides an opportunity to conduct unique science experiments above Earth’s atmosphere and is a pipeline for the technology and personnel essential to future space astrophysics, heliophysics, and atmospheric science missions. In this paper, we describe three astronomy payloads developed (or in development) by the Ultravio…
Giada: its Status after the Rosetta Cruise Phase and On-Ground Activity in Support of the Encounter with Comet 67P/CHURYUMOV-GERASIMENKO
Lamy, P.; Fulle, M.; Rodrigo, R. +33 more
GIADA (Grain Impact Analyser and Dust Accumulator) on-board the Rosetta mission to comet 67P/Churyumov-Gerasimenko was designed to study the physical and dynamical properties of dust particles ejected by the comet during the encounter. In this paper we report the results of the analysis of data collected by GIADA during the past seven years of the…
