Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Adolfo S. Carvalho, Gregory J. Herczeg, Kevin France, Lynne A. Hillenbrand, | Summary: The eruptive YSO FU Ori is the eponym of its variable class. FU Ori stars are known to undergo outbursts with amplitudes of $>4$ magnitudes in the $V$ band and durations of several […]
Kavli Affiliate: Michael D. Gladders | First 5 Authors: Erik Solhaug, Hsiao-Wen Chen, Mandy C. Chen, Fakhri Zahedy, Max Gronke | Summary: The hydrogen Lyman-alpha (Lya) emission line, the brightest spectral feature of a photoionized gas, is considered an indirect tracer of the escape of Lyman continuum (LyC) photons, particularly when the intergalactic medium is […]

Kavli Affiliate: David A. Principe | First 5 Authors: Aneta Siemiginowska, Douglas Burke, Hans Moritz Günther, Nicholas P. Lee, Warren McLaughlin | Summary: We present an overview of Sherpa, an open source Python project, and discuss its development history, broad design concepts and capabilities. Sherpa contains powerful tools for combining parametric models into complex expressions […]
Kavli Affiliate: Shigeki Matsumoto | First 5 Authors: Shigeki Matsumoto, Jie Sheng, Chuan-Yang Xing, , | Summary: Dark matter with mass in the crossover range between wave dark matter and particle dark matter, around $(10^{-3},, 10^3),$eV, remains relatively unexplored by terrestrial experiments. In this mass regime, dark matter scatters coherently with macroscopic objects. The effect […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Perseas Christodoulidis, Jinn-Ouk Gong, Wei-Chen Lin, Maria Mylova, Misao Sasaki | Summary: Chern-Simons gravity is known to suffer from graviton ghost production during inflation, which suppresses the parity-violating power spectrum at scales relevant to cosmic microwave background observations. In this work, we show that allowing the initial […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Lulu Zhang, Ismael García-Bernete, Chris Packham, Fergus R. Donnan, Dimitra Rigopoulou | Summary: We analyze JWST MIRI/MRS IFU observations of three Seyferts and showcase the intriguing polycyclic aromatic hydrocarbon (PAH) emission characteristics in regions of $sim 500,rm pc$ scales over or around their active galactic nuclei (AGN).
