Wide field Slitless Spectroscopy with JWST's MIRI
Andreea Petric, Sarah Kendrew, David Law +12
We present a snapshot of the ongoing efforts to obtain background-subtracted, wavelength-, and flux-calibrated spectra taken with the new Wide-Field Slitless Spectroscopy (WFSS) mo…
Enhancing the performance and capabilities of the MIRI instrument on JWST
S. Kendrew, M. Engesser, K. Rowlands +23
MIRI, the Mid-Infrared Instrument on the James Webb Space Telescope, is the only instrument sensitive to wavelengths longward of 5 um on the observatory. In this regime, MIRI bring…
Worlds Next Door: A Candidate Giant Planet Imaged in the Habitable Zone of Cen A. I. Observations, Orbital and Physical Properties, and Exozodi Upper Limits
Charles Beichman, Aniket Sanghi, Dimitri Mawet +27
We report on coronagraphic observations of the nearest solar-type star, Cen A, using the MIRI instrument on the James Webb Space Telescope. With three epochs of observation (Au…
The James Webb Space Telescope Absolute Flux Calibration. II. Mid-Infrared Instrument Imaging and Coronagraphy
Karl D. Gordon, G. C. Sloan, Macarena Garcia Marin +11
The absolute flux calibration of the Mid-Infrared Instrument Imaging and Coronagraphy is based on observations of multiple stars taken during the first 2.5 years of JWST operations…
Spatially resolved imaging of the inner Fomalhaut disk using JWST/MIRI
Andras Gaspar, Schuyler Grace Wolff, George H. Rieke +9
Planetary debris disks around other stars are analogous to the Asteroid and Kuiper belts in the Solar System. Their structure reveals the configuration of small bodies and provides…
The James Webb Space Telescope Mission
Jonathan P. Gardner, John C. Mather, Randy Abbott +1004
Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized…
Planet Search with the Keck/NIRC2 Vortex Coronagraph in Ms-band for Vega
Bin B. Ren, Nicole L. Wallack, Spencer A. Hurt +12
Gaps in circumstellar disks can signal the existence of planetary perturbers, making such systems preferred targets for direct imaging observations of exoplanets. Being one of the…
JWST/NIRCam Coronagraphy: Commissioning and First On-Sky Results
Julien H. Girard, Jarron Leisenring, Jens Kammerer +53
In a cold and stable space environment, the James Webb Space Telescope (JWST or "Webb") reaches unprecedented sensitivities at wavelengths beyond 2 microns, serving most fields of…
StraKLIP: A novel pipeline for detection and characterization of close-in faint companions through Karhunen-Loêve Image Processing algorithm
Giovanni M. Strampelli, Laurent Pueyo, Jonathan Aguilar +3
We present a new pipeline developed to detect and characterize faint astronomical companions at small angular separation from the host star using sets of wide-field imaging observa…
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…
HST survey of the Orion Nebula Cluster in the HO 1.4 m absorption band: III. The population of sub-stellar binary companions
Giovanni M. Strampelli, Jonathan Aguilar, Laurent Pueyo +4
We present new results concerning the sub-stellar binary population in the Orion Nebula Cluster (ONC). Using the Karhunen-Loève Image Projection (KLIP) algorithm, we have reprocess…
A deep search for planets in the inner 15 au around Vega
Tiffany Meshkat, Ricky Nilsson, Jonathan Aguilar +12
We present the results of a deep high-contrast imaging search for planets around Vega. Vega is an ideal target for high-contrast imaging because it is bright, nearby, and young wit…
GPI spectra of HR 8799 c, d, and e from 1.5 to 2.4m with KLIP Forward Modeling
Alexandra Z. Greenbaum, Laurent Pueyo, Jean-Baptiste Ruffio +51
We explore KLIP forward modeling spectral extraction on Gemini Planet Imager coronagraphic data of HR 8799, using PyKLIP and show algorithm stability with varying KLIP parameters.…
Project 1640 Observations of the White Dwarf HD 114174 B
E. Bacchus, I. R. Parry, R. Oppenheimer +24
We present the first near infra-red spectrum of the faint white dwarf companion HD 114174 B, obtained with Project 1640. Our spectrum, covering the Y, J and H bands, combined with…
Project 1640 Observations of Brown Dwarf GJ 758 B: Near-Infrared Spectrum and Atmospheric Modeling
R. Nilsson, A. Veicht, P. A. Giorla Godfrey +23
The nearby Sun-like star GJ 758 hosts a cold substellar companion, GJ 758 B, at a projected separation of 30 AU, previously detected in high-contrast multi-band photometr…
Characterization of the Companion to Her
Lewis C. Roberts, Brian D. Mason, Jonathan Aguilar +24
Her is a nearby quadruple system with a G-subgiant primary and several low mass companions arranged in a 2+2 architecture. While the BC components have been well characterized,…
Archival Legacy Investigations of Circumstellar Environments (ALICE): Statistical assessment of point source detections
É. Choquet, L. Pueyo, R. Soummer +5
The ALICE program, for Archival Legacy Investigation of Circumstellar Environment, is currently conducting a virtual survey of about 400 stars, by re-analyzing the HST-NICMOS coron…
