Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Nicole E. Drakos, Bruno Villasenor, Brant E. Robertson, Ryan Hausen, Mark E. Dickinson | Summary: In the next decade, deep galaxy surveys from telescopes such as the James Webb Space Telescope and Roman Space Telescope will provide transformational data sets that will greatly enhance the understanding […]
Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Angelo Caravano, Eiichiro Komatsu, Kaloian D. Lozanov, Jochen Weller, | Summary: We use a non-linear lattice simulation to study a model of axion inflation where the inflaton is coupled to a U(1) gauge field through Chern-Simons interaction. This kind of models have already been studied with a […]

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Kohei Inayoshi, Riouhei Nakatani, Daisuke Toyouchi, Takashi Hosokawa, Rolf Kuiper | Summary: We study the early growth of massive seed black holes (BHs) via accretion in protogalactic nuclei where the stellar bulge component is assembled, performing axisymmetric two-dimensional radiation hydrodynamical simulations. We find that when a seed […]
Kavli Affiliate: Lijing Shao | First 5 Authors: Jin-Ping Zhu, Shichao Wu, Yuan-Pei Yang, Chang Liu, Bing Zhang | Summary: In the second work of this series, we explore the optimal search strategy for serendipitous and gravitational-wave-triggered target-of-opportunity (ToO) observations of kilonovae and optical short-duration gamma-ray burst (sGRB) afterglows from binary neutron star (BNS) mergers, […]
Kavli Affiliate: Roland Vanderspek | First 5 Authors: Akihiko Fukui, Tadahiro Kimura, Teruyuki Hirano, Norio Narita, Takanori Kodama | Summary: We report the discovery of TOI-2285b, a sub-Neptune-sized planet transiting a nearby (42 pc) M dwarf with a period of 27.3 days. We identified the transit signal from the Transiting Exoplanet Survey Satellite photometric data, […]
Kavli Affiliate: Masahiro Takada | First 5 Authors: Mikhail M. Ivanov, Oliver H. E. Philcox, Takahiro Nishimichi, Marko Simonović, Masahiro Takada | Summary: We study the information content of the angle-averaged (monopole) redshift space galaxy bispectrum. The main novelty of our approach is the use of a systematic tree-level perturbation theory model that includes galaxy […]
Kavli Affiliate: Debora Sijacki | First 5 Authors: Francisco Rodríguez Montero, Sergio Martin-Alvarez, Debora Sijacki, Adrianne Slyz, Julien Devriendt | Summary: The cataclysmic explosions of massive stars as supernovae are one of the key ingredients of galaxy formation. However, their evolution is not well understood in the presence of magnetic fields or cosmic rays (CRs). […]
Kavli Affiliate: Ke Wang | First 5 Authors: Yuan Zhou, Sisi Gu, Ke Wang, Gang Cao, Xuedong Hu | Summary: Tunability of an artificial quantum system is crucial to its capability to process quantum information. However, tunability usually poses significant demand on the design and fabrication of a device. In this work, we demonstrate that […]
Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Toshiya Namikawa, Anton Baleato Lizancos, Naomi Robertson, Blake D. Sherwin, Anthony Challinor | Summary: We introduce and validate a delensing framework for the Simons Observatory (SO), which will be used to improve constraints on inflationary gravitational waves (IGWs) by reducing the lensing noise in measurements of the […]
