Discovery of a Candidate Binary Supermassive Black Hole in a Periodic Quasar from Circumbinary Accretion Variability

Kavli Affiliate: R. G. McMahon | First 5 Authors: Wei-Ting Liao, Yu-Ching Chen, Xin Liu, A. Miguel Holgado, Hengxiao Guo | Summary: Binary supermassive black holes (BSBHs) are expected to be a generic byproduct from hierarchical galaxy formation. The final coalescence of BSBHs is thought to be the loudest gravitational wave (GW) siren, yet no […]

Vibronic response of a spin-1/2 state from a carbon impurity in two-dimensional WS$_2$

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Katherine A. Cochrane, Jun-Ho Lee, Christoph Kastl, Jonah B. Haber, Tianyi Zhang | Summary: We demonstrate the creation of a spin-1/2 state via the atomically controlled generation of magnetic carbon radical ions (CRIs) in synthetic two-dimensional transition metal dichalcogenides (TMDs). Hydrogenated carbon impurities located at chalcogen […]

The Scale of Superpartner Masses and Electroweakino Searches at the High-Luminosity LHC

Kavli Affiliate: Carlos E. M. Wagner | First 5 Authors: Jia Liu, Navin McGinnis, Carlos E. M. Wagner, Xiao-Ping Wang, | Summary: Searches for weakly interacting particles is one of the main goals of the high luminosity LHC run. In this work we study the well motivated cases of electroweakinos with mostly Wino and Bino […]

A Synoptic VLBI Technique for Localizing Non-Repeating Fast Radio Bursts with CHIME/FRB

Kavli Affiliate: Kiyoshi Masui | First 5 Authors: Calvin Leung, Juan Mena-Parra, Kiyoshi Masui, Mohit Bhardwaj, P. J. Boyle | Summary: We demonstrate the blind interferometric detection and localization of two fast radio bursts (FRBs) with 2- and 25-arcsecond precision on the 400-m baseline between the Canadian Hydrogen Intensity Mapping Experiment (CHIME) and the CHIME […]

Complex Modulation of Rapidly Rotating Young M Dwarfs: Adding Pieces to the Puzzle

Kavli Affiliate: Saul Rappaport | First 5 Authors: Maximilian N. Günther, David A. Berardo, Elsa Ducrot, Catriona A. Murray, Keivan G. Stassun | Summary: New sets of young M dwarfs with complex, sharp-peaked, and strictly periodic photometric modulations have recently been discovered with Kepler/K2 and TESS data. All of these targets are part of young […]

Probing galaxy evolution in massive clusters using ACT and DES: splashback as a cosmic clock

Kavli Affiliate: Eli Rykoff | First 5 Authors: Susmita Adhikari, Tae-hyeon Shin, Bhuvnesh Jain, Matt Hilton, Eric Baxter | Summary: We measure the projected number density profiles of galaxies and the splashback feature in clusters selected by the Sunyaev–Zeldovich (SZ) effect from the Advanced Atacama Cosmology Telescope (AdvACT) survey using galaxies observed by the Dark […]

Cosmology Intertwined IV: The Age of the Universe and its Curvature

Kavli Affiliate: Wendy Freedman | First 5 Authors: Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu, Yacine Ali-Haimoud, Luca Amendola | Summary: A precise measurement of the curvature of the Universe is of primeval importance for cosmology since it could not only confirm the paradigm of primordial inflation but also help in discriminating between different […]

Cosmology Intertwined I: Perspectives for the Next Decade

Kavli Affiliate: Wendy Freedman | First 5 Authors: Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu, Yacine Ali-Haimoud, Luca Amendola | Summary: The standard $Lambda$ Cold Dark Matter cosmological model provides an amazing description of a wide range of astrophysical and astronomical data. However, there are a few big open questions, that make the standard […]
