First results from the JWST Early Release Science Program Q3D: Turbulent times in the life of a extremely red quasar revealed by NIRSpec IFU
Dominika Wylezalek, Andrey Vayner, David S. N. Rupke +20
Extremely red quasars, with bolometric luminosities exceeding erg s, are a fascinating high-redshift population that is absent in the local universe. They are the…
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…
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…
Dark matter halos and scaling relations of extremely massive spiral galaxies from extended HI rotation curves
Enrico M. Di Teodoro, Lorenzo Posti, S. Michael Fall +6
We present new and archival atomic hydrogen (\hi) observations of \galnum\ of the most massive spiral galaxies in the local Universe (). From 3…
The CO emission in the Taffy Galaxies (UGC 12914/5) at 60pc resolution-I: The battle for star formation in the turbulent Taffy Bridge
P. N. Appleton, B. Emonts, U. Lisenfeld +8
We present ALMA observations at a spatial resolution of 0.2 arcsec (60 pc) of CO emission from the Taffy galaxies (UGC 12914/5). The observations are compared with narrow-band Pa$α…
The Near-Infrared Spectrograph (NIRSpec) on the James Webb Space Telescope III. Integral-field spectroscopy
T. Böker, S. Arribas, N. Lützgendorf +28
The Near-Infrared Spectrograph (NIRSpec) on the James Webb Space Telescope (JWST) offers the first opportunity to use integral-field spectroscopy from space at near-infrared wavele…
Extremely massive disc galaxies in the nearby Universe form through gas-rich minor mergers
R. A. Jackson, S. Kaviraj, G. Martin +5
In our hierarchical structure-formation paradigm, the observed morphological evolution of massive galaxies -- from rotationally-supported discs to dispersion-dominated spheroids --…
Detection of a Superluminous Spiral Galaxy in the Heart of a Massive Galaxy Cluster
Akos Bogdan, Lorenzo Lovisari, Patrick Ogle +5
It is well established that brightest cluster galaxies (BCGs), residing in the center of galaxy clusters, are typically massive and quenched galaxies with cD or elliptical morpholo…
