Kavli Affiliate: Linhua Jiang | First 5 Authors: Zijian Zhang, Linhua Jiang, Weiyang Liu, Luis C. Ho, Kohei Inayoshi | Summary: James Webb Space Telescope (JWST) has revealed a population of red and compact objects with a unique V-shape SED at z >= 4 known as Little Red Dots (LRDs). Most of the LRDs with […]
Kavli Affiliate: Steven Allen | First 5 Authors: Chloe Taylor, Daniel Wilkins, Steven Allen, , | Summary: REJ1034+396 is one of the few active galactic nuclei with a significant quasi-periodic oscillation (QPO). The QPO has been observed in over 1 Ms of XMM-Newton observations spanning over a decade. We investigate the power spectral density function […]
Kavli Affiliate: Linhua Jiang | First 5 Authors: Jie Chen, Linhua Jiang, Shengxiu Sun, Zijian Zhang, Mouyuan Sun | Summary: We present a new method to calculate bolometric luminosities for unobscured, type 1 quasars with multi-band photometric data. Bolometric luminosity is a fundamental property to understand quasars and it is commonly estimated from monochromatic luminosities […]
Kavli Affiliate: Michael M. Fausnaugh | First 5 Authors: Joseph D. Twicken, Jon M. Jenkins, Douglas A. Caldwell, Benjamin M. Tofflemire, Marziye Jafariyazani | Summary: We report the delivery to the Mikulski Archive for Space Telescopes (MAST) of tables containing Root Mean Square (RMS) Combined Differential Photometric Precision (CDPP) values for all TESS 2-min cadence […]
Kavli Affiliate: Ke Wang | First 5 Authors: Ziteng Wang, Jiarun Zhong, Ke Wang, Zitian Zhu, Zehang Bao | Summary: Vortex interactions are commonly observed in atmospheric turbulence, plasma dynamics, and collective behaviors in biological systems. However, accurately simulating these complex interactions is highly challenging due to the need to capture fine-scale details over extended […]
Kavli Affiliate: Li Xin Li | First 5 Authors: Yifan Li, Xin Li, Tianqin Li, Wenbin He, Yu Kong | Summary: Vision foundation models (VFMs) have demonstrated remarkable performance across a wide range of downstream tasks. While several VFM adapters have shown promising results by leveraging the prior knowledge of VFMs, we identify two inefficiencies […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Bryce Wedig, Tansu Daylan, Simon Birrer, Francis-Yan Cyr-Racine, Cora Dvorkin | Summary: Galaxy-galaxy strong gravitational lenses can constrain dark matter models and the Lambda Cold Dark Matter cosmological paradigm at sub-galactic scales. Currently, there is a dearth of images of these rare systems with high signal-to-noise […]
Kavli Affiliate: Peter W. Graham | First 5 Authors: Peter W. Graham, Davide Racco, , , | Summary: The QCD axion has important connections to early universe cosmology. For example, it is often said that isocurvature limits rule out a combination of high axion decay constant, $f_a$, and high inflationary Hubble scale, $H_I$. High scales […]
Kavli Affiliate: Michael McDonald | First 5 Authors: Laurel White, Michael McDonald, Francesco Ubertosi, Massimo Gaspari, Julie Hlavacek-Larrondo | Summary: We present a new 8.5 ks Chandra observation of Abell 1885, obtained as part of the Cluster Evolution Reference Ensemble At Low-z (CEREAL) survey of ~200 low-z galaxy groups and clusters. These data reveal that […]
Kavli Affiliate: Debora Sijacki | First 5 Authors: Sergio Martin-Alvarez, Debora Sijacki, Martin G. Haehnelt, Alice Concas, Yuxuan Yuan | Summary: Dwarf galaxies provide powerful laboratories for studying galaxy formation physics. Their early assembly, shallow gravitational potentials, and bursty, clustered star formation histories make them especially sensitive to the processes that regulate baryons through multi-phase […]
