Analyzing the Atmospheric Dispersion Correction of the Gemini Planet Imager: residual dispersion above design requirements

Posted by dbos April 9, 2024April 22, 2024Stanford

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Malachi Noel, Jason J. Wang, Bruce Macintosh, Katie Crotts, Christian Marois | Summary: The Atmospheric Dispersion Corrector (ADC) of the Gemini Planet Imager (GPI) corrects the chromatic dispersion caused by differential atmospheric refraction (DAR), making it an important optic for exoplanet observation. Despite requiring less than 5 […]

JADES: Primaeval Lyman-$mathrmα$ emitting galaxies reveal early sites of reionisation out to redshift $z sim 9$

Posted by dbos Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Joris Witstok, Roberto Maiolino, Renske Smit, Gareth C. Jones, Andrew J. Bunker | Summary: $require{mediawiki-texvc}$Given the sensitivity of the resonant Lyman-$mathrm{alpha}$ (Ly$mathrm{alpha}$) transition to absorption by neutral hydrogen, observations of Ly$mathrm{alpha}$ emitting galaxies (LAEs) have been widely used to probe the ionising capabilities of reionisation-era galaxies and […]

eDIG-CHANGES II: Project Design and Initial Results on NGC 3556

Posted by dbos April 8, 2024April 22, 2024Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Jiang-Tao Li, Li-Yuan Lu, Zhijie Qu, Robert A. Benjamin, Joel N. Bregman | Summary: The extraplanar diffuse ionized gas (eDIG) represents ionized gases traced by optical/UV lines beyond the stellar extent of galaxies. We herein introduce a novel multi-slit narrow-band spectroscopy method to conduct spatially resolved spectroscopy […]

Measurement of the $e^+e^- to π^+π^-π^0$ cross section in the energy range 0.62-3.50 GeV at Belle II

Posted by dbos Tokyo

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, L. Aggarwal, H. Aihara, N. Akopov | Summary: We report a measurement of the $e^+e^- to pi^+pi^-pi^0$ cross section in the energy range from 0.62 to 3.50 GeV using an initial-state radiation technique. We use an $e^+e^-$ data sample corresponding to 191 […]

Strictly-ID-Preserved and Controllable Accessory Advertising Image Generation

Posted by dbos April 7, 2024Peking

Kavli Affiliate: Jiansheng Chen | First 5 Authors: Youze Xue, Binghui Chen, Yifeng Geng, Xuansong Xie, Jiansheng Chen | Summary: Customized generative text-to-image models have the ability to produce images that closely resemble a given subject. However, in the context of generating advertising images for e-commerce scenarios, it is crucial that the generated subject’s identity […]
