SDSO1 is a Shocked Ghost Planetary Nebula in Front of M 31
Patrick Ogle, Mark Petersen, R. Michael Rich +12
We present new, deep narrowband imagery and discuss the nature of SDSO 1, the large [O III]-emitting nebula centered 1.5 degrees SE of M 31. We find strong evidence to support the…
HH 270/110 as a jet/shear layer interaction
A. C. Raga, A. Noriega-Crespo, A. Castellanos-Ramirez +5
New observations obtained with JWST of the proto-stellar HH~270 jet and the "deflected" HH 110 system, show that HH 110 has a morphology of a series of distorted working surfaces.…
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…
The James Webb Space Telescope Absolute Flux Calibration. III. Mid-Infrared Instrument Medium Resolution IFU Spectrometer
David R. Law, Ioannis Argyriou, Karl D. Gordon +7
We describe the spectrophotometric calibration of the Mid-Infrared Instrument's (MIRI) Medium Resolution Spectrometer (MRS) aboard the James Webb Space Telescope (JWST). This calib…
JWST observations of the Horsehead photon-dominated region I. First results from multi-band near- and mid-infrared imaging
A. Abergel, K. Misselt, K. D. Gordon +14
The JWST has captured the sharpest IR images ever taken of the Horsehead nebula, a prototypical moderately irradiated PDR that is fully representative of most of the UV-illuminated…
PROJECT-J: JWST observations of HH46~IRS and its outflow. Overview and first results
B. Nisini, M. G. Navarro, T. Giannini +23
We present the first results of the JWST program PROJECT-J (PROtostellar JEts Cradle Tested with JWST ), designed to study the Class I source HH46 IRS and its outflow through NIRSp…
