$J$-factor estimation of Draco, Sculptor and Ursa Minor dwarf spheroidal galaxies with the member/foreground mixture model

Posted by klaurent Tokyo

Kavli Affiliate: Shigeki Matsumoto | First 5 Authors: Shun-ichi Horigome, Kohei Hayashi, Masahiro Ibe, Miho N. Ishigaki, Shigeki Matsumoto | Summary: Dwarf spheroidal galaxies (dSphs) are promising targets of indirect detection experiments searching for dark matter (DM) at present universe. Toward robust prediction for the amount of signal flux originating in DM annihilation inside dSphs, […]

Multiwavelength Follow-up of the Hyperluminous Intermediate-mass Black Hole Candidate 3XMM J215022.4-055108

Posted by klaurent MIT

Kavli Affiliate: Ronald A. Remillard | First 5 Authors: Dacheng Lin, Jay Strader, Aaron J. Romanowsky, Jimmy A. Irwin, Olivier Godet | Summary: We recently discovered the X-ray/optical outbursting source 3XMM J215022.4-055108. It was best explained as the tidal disruption of a star by an intermediate-mass black hole of mass of a few tens of […]

Observation of an antiferromagnetic quantum critical point in high-purity LaNiO$_3$

Posted by klaurent Chicago

Kavli Affiliate: Clarence Chang | First 5 Authors: Changjiang Liu, Vincent F. C. Humbert, Terence Bretz-Sullivan, Gensheng Wang, Deshun Hong | Summary: Amongst the rare-earth perovskite nickelates, LaNiO$_3$ (LNO) is an exception. While the former have insulating and antiferromagnetic ground states, LNO remains metallic and non-magnetic down to the lowest temperatures. It is believed that […]

A two-sided Faulhaber-like formula involving Bernoulli polynomials

Posted by klaurent MIT

Kavli Affiliate: J. S. Villasenor | First 5 Authors: Fernando Barbero G., Juan Margalef-Bentabol, Eduardo J. S. Villaseñor, , | Summary: We give a new identity involving Bernoulli polynomials and combinatorial numbers. This provides, in particular, a Faulhaber-like formula for sums of the form $1^m (n-1)^m + 2^m (n-2)^m + cdots + (n-1)^m 1^m$ for […]

Design of a multi-channel photonic crystal dielectric laser accelerator

Posted by klaurent Stanford

Kavli Affiliate: Robert L. Byer | First 5 Authors: Zhexin Zhao, Dylan S. Black, R. Joel England, Tyler W. Hughes, Yu Miao | Summary: To be useful for most scientific and medical applications, compact particle accelerators will require much higher average current than enabled by current architectures. For this purpose, we propose a photonic crystal […]
