Kavli Affiliate: Jing Wang | First 5 Authors: Zhenyu Ni, Jing Wang, Liying Kang, , | Summary: The $kK_{r+1}$ is the union of $k$ disjoint copies of $(r+1)$-clique. Moon [Canad. J. Math. 20 (1968) 95–102] and Simonovits [Theory of Graphs (Proc. colloq., Tihany, 1996)] independently showed that if $n$ is sufficiently large, then $K_{k-1}vee T_{n-k+1,r}$ […]
Kavli Affiliate: Peter W. Graham | First 5 Authors: Xing Fan, Gerald Gabrielse, Peter W. Graham, Roni Harnik, Thomas G. Myers | Summary: We propose using trapped electrons as high-$Q$ resonators for detecting meV dark photon dark matter. When the rest energy of the dark photon matches the energy splitting of the two lowest cyclotron […]

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Ana Trcka, Maarten Baes, Peter Camps, Anand Utsav Kapoor, Dylan Nelson | Summary: We apply the radiative transfer (RT) code SKIRT on a sample of ~14000 low-redshift (z<= 0.1) galaxies extracted from the TNG50 simulation to enable an apples-to-apples comparison with observations. The RT procedure is calibrated […]
Kavli Affiliate: Sara Seager | First 5 Authors: Steven Giacalone, Courtney D. Dressing, Antonio García Muñoz, Matthew J. Hooton, Keivan G. Stassun | Summary: We report the discovery in TESS data and validation of HD 56414 b (a.k.a. TOI-1228 b), a Neptune-size ($R_{rm p} = 3.71 pm 0.20, R_oplus$) planet with a 29-day orbital period […]
Kavli Affiliate: George Ricker | First 5 Authors: Charles Cadieux, René Doyon, Mykhaylo Plotnykov, Guillaume Hébrard, Farbod Jahandar | Summary: Exploring the properties of exoplanets near or inside the radius valley provides insights on the transition from the rocky super-Earths to the larger, hydrogen-rich atmosphere mini-Neptunes. Here, we report the discovery of TOI-1452 b, a […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Andjelka B. Kovacevic, Viktor Radovic, Dragana Ilic, Luka C. Popovic, Roberto J. Assef | Summary: The Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) will detect an unprecedentedly large sample of actively accreting supermassive black holes with typical accretion disk (AD) sizes of a […]
Kavli Affiliate: Roland Vanderspek | First 5 Authors: Carina M. Persson, Iskra Y. Georgieva, Davide Gandolfi, Lorena Acuña, Artem Aguichine | Summary: Highly irradiated planets in the hot Neptune desert are usually either small (R < 2 Rearth) and rocky or they are gas giants with radii of >1 Rjup. Here, we report on the […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Jason J. Wang, Peter Gao, Jeffrey Chilcote, Julien Lozi, Olivier Guyon | Summary: The atmospheres of gas giant planets are thought to be inhomogeneous due to weather and patchy clouds. We present two full nights of coronagraphic observations of the HR 8799 planets using the CHARIS integral […]
