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 […]

Prospects for probing small-scale dark matter models with pulsars around Sagittarius A*

Posted by dbos Peking

Kavli Affiliate: Lijing Shao | First 5 Authors: Zexin Hu, Lijing Shao, Fupeng Zhang, , | Summary: Future observations with next-generation large-area radio telescopes are expected to discover radio pulsars (PSRs) closely orbiting around Sagittarius~A* (Sgr~A*), the supermassive black hole (SMBH) dwelling at our Galactic Center (GC). Such a system can provide a unique laboratory […]
