Exploring the sub-Neptune frontier with JWST. [PDF]
Proc Natl Acad Sci U S A Sub-Neptune planets, with sizes and masses between those of Earth and Neptune, dominate the exoplanet population. Sub-Neptunes are expected to be the most diverse family of the exoplanet population, potentially including rocky gas dwarfs, water worlds, and mini-Neptunes, with a wide range of atmospheric, surface, and interior conditions ...Madhusudhan N, Holmberg M, Constantinou S, Cooke GJ. +3 moreeuropepmc +6 more sourcesMid-infrared Spectroscopy of Protonated Benzonitrile, 2-Cyanonaphthalene, and 9-Cyanoanthracene for Astrochemical Consideration.

ChemphyschemExperimental infrared absorption spectra of three protonated cyano‐substituted PAHs measured by infrared multiple photon dissociation using the free‐electron laser Free‐Electron Laser for Infrared eXperiments are studied. These spectra are compared to an emission spectrum measured by JWST, and the largest measured protonated cyano‐PAH, cyanoanthracene, Rasmussen AP, Rossi C, Gans B, Finazzi L, Oomens J, Berden G, Jacovella U. +6 moreeuropepmc +2 more sourcesJWST’s PEARLS: A JWST/NIRCam View of ALMA Sources [PDF]
The Astrophysical Journal Letters, 2023 Abstract We report the results of James Webb Space Telescope/NIRCam observations of 19 (sub)millimeter sources detected by the Atacama Large Millimeter Array (ALMA). The accurate ALMA positions allowed unambiguous identifications of their NIRCam counterparts. Taking gravitational lensing into account, these represent 16 distinct galaxies Cheng, Cheng, Huang, Jia-Sheng, Smail, Ian, Yan, Haojing, Cohen, Seth H., Jansen, Rolf A., Windhorst, Rogier A., Ma, Zhiyuan, Koekemoer, Anton, Willmer, Christopher N.

Publications of the Astronomical Society of the Pacific, 2023 Abstract The Near Infrared Camera for the James Webb Space Telescope (JWST) is delivering the imagery that astronomers have hoped for ever since JWST was proposed back in the 1990s. In the Commissioning Period that extended from right after launch to early 2022 July, NIRCam has been subjected to a number of performance tests and ...Rieke, Marcia J., Kelly, Douglas M., Misselt, Karl, Stansberry, John, Boyer, Martha, Beatty, Thomas, Egami, Eiichi, Florian, Michael, Greene, Thomas P., Hainline, Kevin, Leisenring, Jarron, Roellig, Thomas, Schlawin, Everett, Sun, Fengwu, Tinnin, Lee, Williams, Christina C., Willmer, Christopher N.

II. Systematic Error Sources in JWST NIRCam Time Series [PDF]
The Astronomical Journal, 2021 Abstract The James Webb Space Telescope (JWST) holds great promise for characterizing atmospheres of transiting exoplanets, potentially providing insights into Earth-sized planets within the habitable zones of M-dwarf host stars if photon-limited performance can be achieved. Here, we discuss the systematic error sources that are expected Everett Schlawin, Jarron Leisenring, Michael W. McElwain, Karl Misselt, Kenneth Don, Thomas P.

The Astronomical JournalAbstract JWST, despite not being designed to observe astrophysical phenomena that vary on rapid timescales, can be an unparalleled tool for such studies. If timing systematics can be controlled, JWST will be able to open up the subsecond infrared timescale regime.Shaw, A.W., Kaplan, D.L., Gandhi, P., Maccarone, T.J., Borowski, E.S., Britt, C.T., Buckley, D.A.H., Burdge, K.B., Charles, P.A., Dhillon, V.S., French, R.G., Heinke, C.O., Hynes, R.I., Knigge, C., Littlefair, S.P., Pawar, D., Plotkin, R.M., Ressler, M.E., Santos-Sanz, P., Shahbaz, T., Sivakoff, G.R., Stevens, A.L. +21 moreopenaire +6 more sourcesJWST Noise Floor.

The Astronomical Journal, 2020 Abstract James Webb Space Telescope (JWST) transmission and emission spectra will provide invaluable glimpses of transiting exoplanet atmospheres, including possible biosignatures. This promising science from JWST, however, will require exquisite precision and understanding of systematic errors that can impact the time series of planets ...Everett Schlawin, Jarron Leisenring, Karl Misselt, Thomas P.

The Astrophysical Journal, 2021 Abstract One of the primary goals for the upcoming James Webb Space Telescope is to observe the first galaxies. Predictions for planned and proposed surveys have typically focused on average galaxy counts, assuming a random distribution of galaxies across the observed field.Charles L.

Publications of the Astronomical Society of the Pacific, 2023 Abstract 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 performance of the spacecraft, telescope, science instruments, and ground system, with an emphasis on differences from pre-launch expectations.Jane Rigby, Marshall Perrin, Michael McElwain, Randy Kimble, Scott Friedman, Matt Lallo, René Doyon, Lee Feinberg, Pierre Ferruit, Alistair Glasse, Marcia Rieke, George Rieke, Gillian Wright, Chris Willott, Knicole Colon, Stefanie Milam, Susan Neff, Christopher Stark, Jeff Valenti, Jim Abell, Faith Abney, Yasin Abul-Huda, D.
