Spectroscopic Time-series Performance of JWST/NIRSpec from Commissioning Observations
Néstor Espinoza, Leonardo Úbeda, Stephan M. Birkmann +22
We report on JWST commissioning observations of the transiting exoplanet HAT-P-14 b, obtained using the Bright Object Time Series (BOTS) mode of the NIRSpec instrument with the G39…
Informed systematic method to identify variable mid and late-T dwarfs
Natalia Oliveros-Gómez, Elena Manjavacas, Afra Ashraf +5
The majority of brown dwarfs show some level of photometric or spectro-photometric variability in different wavelength ranges. This variability allow us to trace the 3D atmospheric…
The In-Flight Noise Performance of the JWST/NIRSpec Detector System
Stephan M. Birkmann, Giovanna Giardino, Marco Sirianni +11
The Near-Infrared Spectrograph (NIRSpec) is one the four focal plane instruments on the James Webb Space Telescope (JWST) which was launched on December 25, 2021. We present the in…
Optical throughput and sensitivity of JWST NIRSpec
G. Giardino, R. Bhatawdekar, S. M. Birkmann +13
To achieve its ambitious scientific goals, the Near-Infrared Spectrograph, NIRSpec, on board the Webb Space Telescope, needs to meet very demanding throughput requirements, here qu…
In-flight performance of the NIRSpec Micro Shutter Array
Timothy D. Rawle, Giovanna Giardino, David E. Franz +33
The NIRSpec instrument on the James Webb Space Telescope (JWST) brings the first multi-object spectrograph (MOS) into space, enabled by a programmable Micro Shutter Array (MSA) of…
In-orbit Commissioning of the Near-Infrared Spectrograph on the James Webb Space Telescope
Torsten Böker, Yasin Abul-Huda, Martin Altenburg +41
The Near-Infrared Spectrograph (NIRSpec) is one of the four focal plane instruments on the James Webb Space Telescope which was launched on Dec. 25, 2021. We present an overview of…
X-SHYNE: X-shooter spectra of young exoplanet analogs. I. A medium-resolution 0.65-2.5 one-shot spectrum of VHS\,1256-1257 b
Simon Petrus, Gaël Chauvin, Mickaël Bonnefoy +10
We present simultaneous 0.65-2.5 microns medium resolution (3300 < R < 8100) VLT/X-Shooter spectra of the young low-mass (19+/-5MJup) L-T transition object VHS 1256-1257 b, a known…
The Science Performance of JWST as Characterized in Commissioning
Jane Rigby, Marshall Perrin, Michael McElwain +623
This paper characterizes the actual science performance of the James Webb Space Telescope (JWST), as determined from the six month commissioning period. We summarize the performanc…
Disentangling the Signatures of Blended-Light Atmospheres in L/T Transition Brown Dwarfs
Afra Ashraf, Daniella C. Bardalez Gagliuffi, Elena Manjavacas +3
We present a technique to identify spectrophotometrically variable L7-T3 brown dwarfs with single-epoch, low-resolution, near-infrared SpeX spectra. We calculated spectral indices…
Tracing the Top-of-the-atmosphere and Vertical Cloud Structure of a fast-rotating late T-dwarf
Elena Manjavacas, Theodora Karalidi, Xianyu Tan +4
Only a handful of late-T brown dwarfs have been monitored for spectro-photometric variability, leaving incomplete the study of the atmospheric cloud structures of the coldest brown…
