Asymptotic limits in class- theories and non-Abelian Hodge theory
Thomas W. Grimm, Amineh Mohseni
We develop a non-Abelian Hodge-theoretic refinement of asymptotic limits in type- class- theories, enriching the geometric description of the degenerating UV curve w…
The JWST Proto-PAH Project: Detection of the methyl radical CH in the highly evolved C-rich object SMP LMC 011
Jialu Li, D. A. García-Hernández, A. Manchado +17
We report the first detection of the neutral methyl radical CH in a highly evolved C-rich object, SMP LMC 011, using JWST MIRI/MRS. CH is well fitted by an excitation tempe…
A JWST transiting survey of FGK stellar limb darkening: empirical evidence for quadratic laws and atmospheric model comparisons
David K. Sing, Joshua D. Lothringer, Jeff A. Valenti +11
We present a study of stellar limb-darkening using JWST transit observations of seven exoplanets orbiting FGK host stars, spanning 4200-6800 K. The wide wavelength coverage and hig…
Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory
Courtney D. Dressing, Danica Adams, Evelyne Alecian +324
The Habitable Worlds Observatory (HWO) is a future NASA flagship mission concept identified by the Astro2020 Decadal Survey as the highest priority for large space missions. HWO sh…
Exoplanet Search and Characterization with the Proposed POET Canadian Space Mission
S. Metchev, J. Rowe, P. Miles-Páez +20
The Photometric Observations of Exoplanet Transits (POET) is a proposed micro-satellite mission dedicated to the characterization and discovery of transiting exoplanets. POET has b…
Detection of CO ice in the planetary nebula NGC 6302
Charmi Bhatt, Simon W. Cao, Jan Cami +20
Using JWST/MIRI observations, we report the detection of CO ice in the dusty torus of the planetary nebula NGC 6302, an environment generally considered hostile to fragile mole…
Observations of AGN-driven feedback: dynamics and ionization of the filaments in M87
Camille Poitras, Marie-Lou Gendron-Marsolais, Valeria Olivares +9
We present a comprehensive kinematic and ionization analysis of the warm ionized filaments ( K) in M87, the central galaxy of the Virgo cluster, using new integral field spec…
The SPACE Program. I. The featureless spectrum of HD 86226 c challenges sub-Neptune atmosphere trends
K. Angelique Kahle, Jasmina Blecic, Reza Ashtari +26
Sub-Neptune exoplanets are the most abundant type of planet known today. As they do not have a Solar System counterpart, many open questions exist about their composition and forma…
Blind search for activity-sensitive lines in the near-infrared using HARPS and NIRPS observations of Proxima and Gl 581
João Gomes da Silva, Elisa Delgado-Mena, Nuno C. Santos +145
Stellar activity variability is one of the main obstacles to the detection of Earth-like planets using the RV method. The aim of this work is to measure the effect of activity in t…
The New Science of Unidentified Aerospace-Undersea Phenomena (UAP)
Kevin H. Knuth, Philippe Ailleris, Hussein Ali Agrama +36
After decades of dismissal and secrecy, it has become clear that a significant number of the world's governments take Unidentified Aerospace-Undersea Phenomena (UAP), formerly know…
UV-Bright Star-Forming Clumps and Their Host Galaxies in UVCANDELS at 0.5 z 1
Alec Martin, Yicheng Guo, Xin Wang +32
Giant star-forming clumps are a prominent feature of star-forming galaxies (SFGs) and contain important clues on galaxy formation and evolution. However, basic demographics of clum…
Optimization and Commissioning of the EPIC Commensal Radio Transient Imager for the Long Wavelength Array
Hariharan Krishnan, Adam P. Beardsley, Judd D. Bowman +4
Next generation aperture arrays are expected to consist of hundreds to thousands of antenna elements with substantial digital signal processing to handle large operating bandwidths…
A broadband thermal emission spectrum of the ultra-hot Jupiter WASP-18b
Louis-Philippe Coulombe, Björn Benneke, Ryan Challener +73
Close-in giant exoplanets with temperatures greater than 2,000 K (''ultra-hot Jupiters'') have been the subject of extensive efforts to determine their atmospheric properties using…
Searching for a Galactic component in the IceCube track-like neutrino events
Gregory S. Vance, Kimberly L. Emig, Cecilia Lunardini +1
Searches for spatial associations between high-energy neutrinos observed at the IceCube Neutrino Observatory and known astronomical objects may hold the key to establishing the neu…
Effects of model incompleteness on the drift-scan calibration of radio telescopes
Bharat K. Gehlot, Daniel C. Jacobs, Judd D. Bowman +76
Precision calibration poses challenges to experiments probing the redshifted 21-cm signal of neutral hydrogen from the Cosmic Dawn and Epoch of Reionization (z~30-6). In both inter…
SED Analysis of 13 Spectroscopically Confirmed Galaxies at z6 to Constrain UV-Slope, Model Dust Attenuation and Escape Fractions
Junehyoung Jeon, Rogier Windhorst, Seth H. Cohen +8
The reionization of the hydrogen in the Universe is thought to have completed by redshift . To probe this era, galaxy observations in the Subaru Deep Field (SDF) have…
