Prospects for constraining quasar ages with fiber spectrographs: Quasar-induced Ly$α$ emission from the intergalactic medium

Posted by dbos Tokyo

Kavli Affiliate: Masahiro Takada | First 5 Authors: Ryuichiro Hada, Masahiro Takada, Akio K. Inoue, , | Summary: We present a theoretical framework for linking quasar properties, such as quasar age, to the surrounding Ly$alpha$ emission intensity. In particular, we focus on a method for mapping the large-scale structure of Ly$alpha$ emission intensity with galaxy […]

Resolving Clumpy vs. Extended Ly-$α$ In Strongly Lensed, High-Redshift Ly-$α$ Emitters

Posted by dbos Chicago

Kavli Affiliate: Michael Gladders | First 5 Authors: Alexander Navarre, Gourav Khullar, Matthew Bayliss, Håkon Dahle, Michael Florian | Summary: We present six strongly gravitationally lensed Ly-$alpha$ Emitters (LAEs) at $zsim4-5$ with HST narrowband imaging isolating Ly-$alpha$. Through complex radiative transfer Ly-$alpha$ encodes information about the spatial distribution and kinematics of the neutral hydrogen upon […]

Searching for the Highest-z Dual AGN in the Deepest Chandra Surveys

Posted by dbos Stanford

Kavli Affiliate: Steven W. Allen | First 5 Authors: Brandon Sandoval, Adi Foord, Steven W. Allen, Marta Volonteri, Aaron Stemo | Summary: We present an analysis searching for dual AGN among 62 high-redshift ($2.5 < z < 3.5$) X-ray sources selected from publicly available deep Chandra fields. We aim to quantify the frequency of dual […]

In-situ tuning of optomechanical crystals with nano-oxidation

Posted by dbos Caltech

Kavli Affiliate: Oskar Painter | First 5 Authors: Utku Hatipoglu, Sameer Sonar, David P. Lake, Srujan Meesala, Oskar Painter | Summary: Optomechanical crystals are a promising device platform for quantum transduction and sensing. Precise targeting of the optical and acoustic resonance frequencies of these devices is crucial for future advances on these fronts. However, fabrication […]
