Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Anna-Christina Eilers, Ruari Mackenzie, Elia Pizzati, Jorryt Matthee, Joseph F. Hennawi | Summary: We expect luminous ($M_{1450}lesssim-26.5$) high-redshift quasars to trace the highest density peaks in our universe, and therefore to reside in proto-clusters encompassing an abundance of galaxies in close vicinity. Here, we present observations […]

Hennawi | Summary: We expect luminous ($M_{1450}lesssim-26.5$) high-redshift quasars to trace the highest density peaks in the early universe. Here, we present observations of four $zgtrsim6$ quasar fields using JWST/NIRCam in imaging and widefield slitless spectroscopy […]

Kavli Affiliate: Frank Wilczek | First 5 Authors: Frank Wilczek, , , , | Summary: The bulk of this paper centers around the tension between confinement and freedom in QCD. I discuss how it can be understood heuristically as a manifestation of self-adhesive glue and how it fits within the larger contexts of energy-time uncertainty […]

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Calvin Leung, Shion Andrew, Kiyoshi W. Masui, Charanjot Brar, Tomas Cassanelli | Summary: One major goal in fast radio burst science is to detect fast radio bursts (FRBs) over a wide field of view without sacrificing the angular resolution required to pinpoint them to their host […]

Kavli Affiliate: Paul L. Schechter | First 5 Authors: Paul L. Schechter, Richard Luhtaru, , , | Summary: In modeling the potentials of quadruply lensed quasars, investigators often employ models for the stellar surface brightness profile of the lensing galaxy for the sole purpose of eliminating its contamination of the light from the quasar images […]

Kavli Affiliate: Paul L. Schechter | First 5 Authors: Paul L. Schechter, Richard Luhtaru, , , | Summary: When a rectangular hyperbola is constructed from the image positions of a quadruply lensed quasar, as proposed by Witt (1996), it passes very close to the the lensing galaxy. The median measured perpendicular offset between the observed […]

Kavli Affiliate: Avi Shporer | First 5 Authors: Canis Li, Avi Shporer, , , | Summary: We perform a systematic search for atmospheric variability in short-period gas-giant planets (hot Jupiters) observed by the Kepler mission, by looking for temporal variability of their secondary eclipse depths. This is motivated by a recent detection of a decrease […]

Kavli Affiliate: Anna Frebel | First 5 Authors: Xiaowei Ou, Anirudh Chiti, Nora Shipp, Joshua D. Simon, Marla Geha | Summary: The Hercules ultra-faint dwarf galaxy (UFD) has long been hypothesized to be tidally disrupting, yet no conclusive evidence has been found for tidal disruption owing partly to difficulties in identifying Hercules member stars. In […]
