A Taxonomy for the Configurations of Quadruply Lensed Quasars

Kavli Affiliate: Paul L. Schechter | First 5 Authors: Paul L. Schechter, , , , | Summary: A simple, novice-friendly scheme for classifying the image configurations of quadruply lensed quasars is proposed. With only six classes, it is intentionally coarse-grained. Readers are invited to test drive the scheme on a sample of 12 quadruply lensed […]

The Astrophysical Distance Scale: V. A 2% Distance to the Local Group Spiral M33 via the JAGB Method, Tip of the Red Giant Branch, and Leavitt Law

Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Abigail J. Lee, Laurie Rousseau-Nepton, Wendy L. Freedman, Barry F. Madore, Maria-Rosa L. Cioni | Summary: The J-region asymptotic giant branch (JAGB) method is a new standard candle that is based on the stable intrinsic J-band magnitude of color-selected carbon stars, and has a precision comparable […]

Split personalities in Bayesian Neural Networks: the case for full marginalisation

Kavli Affiliate: Anthony Lasenby | First 5 Authors: David Yallup, Will Handley, Mike Hobson, Anthony Lasenby, Pablo Lemos | Summary: The true posterior distribution of a Bayesian neural network is massively multimodal. Whilst most of these modes are functionally equivalent, we demonstrate that there remains a level of real multimodality that manifests in even the […]

FaceMAE: Privacy-Preserving Face Recognition via Masked Autoencoders

Kavli Affiliate: Zheng Zhu | First 5 Authors: Kai Wang, Bo Zhao, Xiangyu Peng, Zheng Zhu, Jiankang Deng | Summary: Face recognition, as one of the most successful applications in artificial intelligence, has been widely used in security, administration, advertising, and healthcare. However, the privacy issues of public face datasets have attracted increasing attention in […]

The Ages of Optically Bright Sub-Clusters in the Serpens Star-Forming Region

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Xingyu Zhou, Gregory J. Herczeg, Yao Liu, Min Fang, Michael Kuhn | Summary: The Serpens Molecular Cloud is one of the most active star-forming regions within 500 pc, with over one thousand of YSOs at different evolutionary stages. The ages of the member stars inform us […]

High-precision temperature monitoring system for room-temperature equipment in astrophysical observations

Kavli Affiliate: Nobuhiko Katayama | First 5 Authors: Daiki Tanabe, Masaya Hasegawa, Masashi Hazumi, Nobuhiko Katayama, Shuhei Kikuchi | Summary: We present a precise thermometry system to monitor room-temperature components of a telescope for radio-astronomy such as cosmic microwave background (CMB) observation. The system realizes precision of 1 mK${rm sqrt{s}}$ on a timescale of 20 […]

CMB power spectra and cosmological parameters from Planck PR4 with CamSpec

Kavli Affiliate: George Efstathiou | First 5 Authors: Erik Rosenberg, Steven Gratton, George Efstathiou, , | Summary: We present angular power spectra and cosmological parameter constraints derived from the Planck PR4 (NPIPE) maps of the Cosmic Microwave Background. NPIPE, released by the Planck Collaboration in 2020, is a new processing pipeline for producing calibrated frequency […]
