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…
Segment-level thermal sensitivity analysis for exo-Earth coronagraphy with segmented space telescopes
Ananya Sahoo, Laurent Pueyo, Iva Laginja +5
The paper develops a thermal stability error budget for segmented space telescopes, linking temperature gradients on individual mirror segments to wavefront errors and defining seg…
JWST Spectra Indicate a Large Mass of Postshock Dust Formed by SN 2010jl
Nathan Smith, Melissa Shahbandeh, Ori D. Fox +22
The paper reports JWST mid‑infrared spectra of the Type IIn supernova SN 2010jl 13 years after explosion, revealing a large (~0.2 M☉) mass of warm dust formed in the post‑shock reg…
CATKit2-HCI: a collaborative framework for advancing high-contrast coronagraph testbeds
Rémi Soummer, Iva Laginja, Emiel H. Por +19
High-contrast exoplanet imaging requires dedicated laboratory testbeds for the development and validation of coronagraph architectures, wavefront sensing and control methods, calib…
Impact of segmented deformable mirrors on high-contrast testbeds for exoplanet imaging with future large space telescopes: contrast stability assessment on the HiCAT bench
Benjamin Buralli, Mamadou N'Diaye, Raphaël Pourcelot +13
We investigate the stability of a segmented deformable mirror (DM) on high-contrast testbeds and its impact on the images produced with coronagraphs. Segmented apertures are promis…
Very Late-Time JWST and Keck Spectra of the Oxygen-Rich Supernova 1995N
Geoffrey C. Clayton, R. Wesson, Ori D. Fox +43
We present new {\it JWST}/MIRI MRS and Keck spectra of SN 1995N obtained in 2022--2023, more than 10,000 days after the supernova (SN) explosion. These spectra are among the latest…
