Kavli Affiliate: Nobuhiko Katayama | First 5 Authors: Ryota Takaku, Qi Wen, Scott Cray, Mark Devlin, Simon Dicker | Summary: We fabricated a 302 mm diameter low-pass filter made of alumina that has an anti-reflection coating (ARC) made with laser-ablated sub-wavelength structures (SWS). The filter has been integrated into and is operating with the MUSTANG2 […]
Kavli Affiliate: Qingjuan Yu | First 5 Authors: M. Ghasemi-Nodehi, Chandrachur Chakraborty, Qingjuan Yu, Youjun Lu, | Summary: We examine the possibility for the existence of gravitomagnetic monopole ($n_*$) in M87* by using the results obtained from its first Event Horizon Telescope image. By numerically deducing the shadow sizes in Kerr-Taub-NUT (KTN) spacetime, we show […]
Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Fupeng Zhang, Xian Chen, Lijing Shao, Kohei Inayoshi, | Summary: We study the stellar binary black holes (BBHs) inspiralling/merging in galactic nuclei based on our numerical method GNC. We find that $3-40%$ of all new born BBHs will finally merge due to various dynamical effects. In a […]
Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: Toshiyuki Kobayashi, , , , | Summary: We prove a geometric criterion for the bounded multiplicity property of "small" infinite-dimensional representations of real reductive Lie groupsin both induction and restrictions. Applying the criterion to symmetric pairs, we give a full description of the triples $H subset G […]
Kavli Affiliate: Christopher Burke | First 5 Authors: Bryson Cale, Michael Reefe, Peter Plavchan, Angelle Tanner, Eric Gaidos | Summary: We present updated radial-velocity (RV) analyses of the AU Mic system. AU Mic is a young (22 Myr) early M dwarf known to host two transiting planets – $P_{b}sim8.46$ days, $R_{b}=4.38_{-0.18}^{+0.18} R_{oplus}$, $P_{c}sim18.86$ days, $R_{c}=3.51_{-0.16}^{+0.16} […]
Kavli Affiliate: Linhua Jiang | First 5 Authors: Jinyi Yang, Feige Wang, Xiaohui Fan, Aaron J. Barth, Joseph F. Hennawi | Summary: We report the results of near-infrared spectroscopic observations of 37 quasars in the redshift range $6.3< zle7.64$, including 32 quasars at $z>6.5$, forming the largest quasar near-infrared spectral sample at this redshift. The […]
Kavli Affiliate: Max Tegmark | First 5 Authors: Ziming Liu, Yunyue Chen, Yuanqi Du, Max Tegmark, | Summary: Integrating physical inductive biases into machine learning can improve model generalizability. We generalize the successful paradigm of physics-informed learning (PIL) into a more general framework that also includes what we term physics-augmented learning (PAL). PIL and PAL […]
Kavli Affiliate: Nicola Omodei | First 5 Authors: Melissa Pesce-Rollins, Nicola Omodei, Vahe’ Petrosian, Francesco Longo, | Summary: High-energy solar flares have shown to have at least two distinct phases: prompt-impulsive and delayed-gradual. Identifying the mechanism responsible for accelerating the electrons and ions and the site at which it occurs during these two phases is […]
Kavli Affiliate: Daniel Holz | First 5 Authors: Douglas Tucker, Matthew Wiesner, Sahar Allam, Marcelle Soares-Santos, Clecio de Bom | Summary: On 2019 August 14 at 21:10:39 UTC, the LIGO/Virgo Collaboration (LVC) detected a possible neutron star-black hole merger (NSBH), the first ever identified. An extensive search for an optical counterpart of this event, designated […]
Kavli Affiliate: Ran Wang | First 5 Authors: Yunjing Wu, Zheng Cai, Marcel Neeleman, Kristian Finlator, Shiwu Zhang | Summary: The physical and chemical properties of the circumgalactic medium (CGM) at $zgtrsim6$ have been studied successfully through the absorption in the spectra of background Quasi-Stellar Objects (QSOs). One of the most crucial questions is to […]
