GW250114: testing Hawking's area law and the Kerr nature of black holes
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1785
The gravitational-wave signal GW250114 was observed by the two LIGO detectors with a network matched-filter signal-to-noise ratio of 80. The signal was emitted by the coalescence o…
Binomial series and complex difference equations
Katsuya Ishizaki, Zhi-Tao Wen
We consider properties of binomial series , where and the convergence of binomial series in the com…
Computerized adaptive testing: implementation issues
Margit Antal, Levente Erős, Attila Imre
One of the fastest evolving field among teaching and learning research is students' performance evaluation. Computer based testing systems are increasingly adopted by universities.…
On arc-disjoint Hamiltonian cycles in De Bruijn graphs
Zoltán Kása
We give two equivalent formulations of a conjecture [2,4] on the number of arc-disjoint Hamiltonian cycles in De Bruijn graphs.
The Discovery of Cepheids and a Distance to NGC 5128
Laura Ferrarese, Jeremy R. Mould, Peter B. Stetson +3
We discuss a new distance to NGC 5128 (Centaurus A) based on Cepheid variables observed with the Hubble Space Telescope. Twelve F555W (V) and six F814W (I) epochs of cosmic-ray-spl…
The Centers of Early-Type Galaxies with HST. V. New WFPC2 Photometry
Tod R. Lauer, S. M. Faber, Karl Gebhardt +14
We analyze HST+WFPC2 images of 77 early-type galaxies. Brightness profiles are classed into "core" or "power-law" forms. Cores are typically rounder than power-law galaxies. Nearly…
