Cool Embeddings: Predicting Galaxy Cluster Cooling Times in IllustrisTNG and TNG-Cluster with AstroCLIP
Rawan Karam, Carter Lee Rhea, Julie Hlavacek-Larrondo +4
Foundation models trained on optical astronomical data have not previously been applied to X-ray cluster thermodynamics. We show that embeddings from AstroCLIP, a contrastive visio…
Simultaneous PSF Matching via Dual Kernel Optimization
Carter Lee Rhea, Pieter Van Dokkum, Roberto Abraham +6
Standard point spread function (PSF) matching algorithms consider one image as the reference and aim to find a convolution kernel such that, when applied to the reference image, th…
Using CFHT's SITELLE to Probe the Long-Sought Supernova Remnant Shell in the Crab Nebula
Lucas V. da Conceição, Janette Suherli, Samar Safi-Harb +3
We present deep, wide-field integral field spectroscopy of the Crab nebula obtained with the imaging Fourier transform spectrometer SITELLE at the Canada--France--Hawaii Telescope…
High-spectral-resolution Observations of the [S II] Emission-line Doublet in the Filamentary Nebula Surrounding NGC 1275
Benjamin Vigneron, Julie Hlavacek-Larrondo, Carter Lee Rhea +10
We analyze new high-spectral resolution SITELLE observations (R = = 7000) of the filamentary nebula surrounding NGC 1275, central galaxy of the Perseus cluster. We present h…
Numerous bow shocks in the outer Helix Nebula
Pieter van Dokkum, Roberto Abraham, William P. Bowman +5
Near the end of their lives, low- and intermediate-mass stars expel metal-enriched material in winds and outflows, ultimately producing planetary nebulae (PNe). The ejected materia…
Mapping Gas Accretion and Stellar Kinematics to Sub-kiloparsec Scales in NGC 4696 with JWST/NIRSpec
Mathieu Marquis, Julie Hlavacek-Larrondo, Olivia Pereira +35
We present JWST/NIRSpec IFU spectroscopy of the central pc () of NGC 4696, the BCG in the Centaurus cluster. Leveraging the (…
