Discovery of Dying Active Galactic Nucleus in Arp 187: Experience of Drastic Luminosity Decline within years
Kohei Ichikawa, Junko Ueda, Hyun-Jin Bae +4
Arp 187 is one of the fading active galactic nuclei (AGN), whose AGN activity is currently decreasing in luminosity. We investigate the observational signatures of AGN in Arp 187,…
Tunable Magnetism of Transition Metal Nanostructures by Hydrogenated Graphene
T. Tsevelmaa, Chunfeng, D. Odkhuu +2
Controlling magnetism of transition metal atoms by pairing with electronic states of graphene is intriguing. Herein, through first - principle computation we explore the possib…
Properties of eigenvalues and some regularities on fractional -Laplacian with singular weights
Ky Ho, Inbo Sim
We provide fundamental properties of the first eigenpair for fractional -Laplacian eigenvalue problems under singular weights, which is related to Hardy type inequality, and als…
Positive solutions of semipositone elliptic problems with critical Trudinger-Moser nonlinearities
Kanishka Perera, Inbo Sim
We prove the existence of a positive solution to a semipositone -Laplacian problem with a critical Trudinger-Moser nonlinearity. The proof is based on obtaining uniform $C^{1,α}…
Universal mixed sums of generalized - and -gonal numbers
Jangwon Ju, Byeong-Kweon Oh
An integer of the form for an integer , is called a generalized -gonal number. For positive integers and ,…
Enhanced perpendicular magnetocrystalline anisotropy energy in an artificial magnetic material with bulk spin-momentum coupling
Abdul-Muizz Pradipto, Kay Yakushiji, Woo Seung Ham +8
We systematically investigate the perpendicular magnetocrystalline anisotropy (MCA) in CoPt/Pd-based multilayers. Our magnetic measurement data shows that the asymmetric Co/Pd/P…
