Kavli Affiliate: Huawei Zhang | First 5 Authors: Yang Huang, Qingzheng Li, Huawei Zhang, Xinyi Li, Weixiang Sun | Summary: In this letter, we report the discovery of an intriguing HVS (J1443+1453) candidate that is probably from the Sagittarius Dwarf Spheroidal galaxy (Sgr dSph). The star is an old and very metal-poor low-mass main-sequence turn-off […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Lea A. Hirsch, Lee Rosenthal, Benjamin J. Fulton, Andrew W. Howard, David R. Ciardi | Summary: We explore the impact of outer stellar companions on the occurrence rate of giant planets detected with radial velocities. We searched for stellar and planetary companions to a volume-limited sample of […]
Kavli Affiliate: Erin Kara | First 5 Authors: Michael McDonald, Brian R. McNamara, Michael S. Calzadilla, Chien-Ting Chen, Massimo Gaspari | Summary: We present a study of the relationship between black hole accretion rate (BHAR) and star formation rate (SFR) in a sample of giant elliptical galaxies. These galaxies, which live at the centers of […]
Kavli Affiliate: Mohammad Mirhosseini | First 5 Authors: Farzad B. Faramarzi, Peter K. Day, Jacob Glasby, Sasha Sypkens, Marco Colangelo | Summary: Superconducting qubits are widely used in quantum computing research and industry. We describe a superconducting kinetic inductance qubit (and introduce the term Kineticon to describe it) operating at W-band frequencies with a nonlinear […]
Kavli Affiliate: Anton Akhmerov | First 5 Authors: Kostas Vilkelis, Lin Wang, Anton Akhmerov, , | Summary: Recent measurements of the out-of-plane magnetoresistance of delafossites (PdCoO$_2$ and PtCoO$_2$) observed oscillations closely resembling the Aharonov-Bohm effect. Here, we show that the magnetoresistance oscillations are explained by the Bloch-like oscillations of the out-of-plane electron trajectories. We develop […]
Kavli Affiliate: Anton Akhmerov | First 5 Authors: Kostas Vilkelis, Lin Wang, Anton Akhmerov, , | Summary: Recent measurements of the out-of-plane magnetoresistance of delafossites (PdCoO$_2$ and PtCoO$_2$) observed oscillations which closely resemble the Aharanov-Bohm effect. We develop a semiclassical theory of these oscillations and show that they are a consequence of the quasi-2D dispersion […]
Kavli Affiliate: E. P. S. Shellard | First 5 Authors: Philip Clarke, E. P. S. Shellard, , , | Summary: Calculating the primordial bispectrum predicted by a model of inflation and comparing it to what we see in the sky is very computationally intensive, necessitating layers of approximations and limiting the models which can be […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Guillem Domènech, Chunshan Lin, Misao Sasaki, , | Summary: We calculate the gravitational waves (GWs) induced by the density fluctuations due to inhomogeneous distribution of primordial black holes (PBHs) in the case where PBHs eventually dominate and reheat the universe by Hawking evaporation. The initial PBH density […]
Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Zeeshan Ahmed, Alapan Chaudhuri, Kunwar Shaanjeet Singh Grover, Hrishi Narayanan, Manasvi Vaidyula | Summary: Computers are known to solve a wide spectrum of problems, however not all problems are computationally solvable. Further, the solvable problems themselves vary on the amount of computational resources they require for being […]
Kavli Affiliate: Linhua Jiang | First 5 Authors: Ravi Joshi, Michele Fumagalli, Raghunathan Srianand, Pasquier Noterdaeme, Patrick Petitjean | Summary: We report the detection of the host galaxy of a damped Ly$alpha$ system (DLA) with log N(HI) $ [rm cm^{-2}]$ = $21.0 pm 0.10$ at $z approx 3.0091$ towards the background quasar SDSS J011852+040644 using […]
