Circular Antenna Array Synthesis Using Multiverse Optimizer by Ahmet Emre Taser, Kerim Guney, Erhan Kurt

“…During the exploration, exploitation, and local search phases of calculation, MVO uses three concepts in cosmology; white hole, black hole, and wormhole. Convergence capability of this nature-inspired algorithm is employed for finding optimum amplitude and position values of CAA elements in order to achieve an array pattern with low maximum sidelobe level (MSL) and minimum circumference. …”

The cosmic timeline implied by the highest redshift quasars by Fulvio Melia

“…Abstract The conventional picture of supermassive black-hole growth in the standard model had already been seriously challenged by the emergence of $$\sim 10^9\;M_\odot $$ ∼ 10 9 M ⊙ quasars at $$z\sim 7.5$$ z ∼ 7.5 , conflicting with the predicted formation of structure in the early $$\varLambda $$ Λ CDM Universe. …”

Improved Clonal Selection Algorithm Based on Biological Forgetting Mechanism by Chao Yang, Bing-qiu Chen, Lin Jia, Hai-yang Wen

“…This part of inactive antibody forms a “black hole” of the antibody set, which is difficult to remove and update in a timely manner, thus affecting the speed at which the algorithm approximates the optimal solution. …”

Kilonova/Macronova Emission from Compact Binary Mergers by Masaomi Tanaka

“…We review current understanding of kilonova/macronova emission from compact binary mergers (mergers of two neutron stars or a neutron star and a black hole). Kilonova/macronova is emission powered by radioactive decays of r-process nuclei and it is one of the most promising electromagnetic counterparts of gravitational wave sources. …”

Shaping the 2010 Strategic Defence & Security Review : An Exercise in Squaring Conflicting Priorities by Jean-Claude Sergeant

“…But the main causes of this black hole are to be found in a combination of factors : the competition between the three Services for securing state-of-the-art equipment, often as a result of the required level of interoperability with American Forces ; the fact that this overspecification trend has been tacitly encouraged by the incapacity or unwillingness of the MoD to scrap an arms project once the main financial gate has been cleared irrespective of its wayward development ; the “cosy relationship” between major defence industrialists, MoD procurement officials and MPs, which often affects the way major contracts are awarded. …”

Neural ODEs for holographic transport models without translation symmetry by Zhuo-Fan Gu, Yu-Kun Yan, Shao-Feng Wu

“…This allows us to determine $$\eta _{\textrm{re}}(\omega )$$ η re ( ω ) of a strongly coupled field theory by the black hole metric and the graviton mass. The latter serves as the bulk dual to the translation symmetry breaking on the boundary. …”

Circular light orbits of a general, static, and spherical symmetrical wormhole with $$Z_2$$ Z 2 symmetry by Naoki Tsukamoto

“…In this study, we categorize the numbers of the circular light orbits of the $$Z_2$$ Z 2 -symmetrical wormhole and their stability from the derivatives of an effective potential at the throat and we investigate the circular light orbits around a Simpson–Visser black-bounce spacetime, a Damour–Solodukhin wormhole spacetime, a Reissner–Nordström black-hole-like wormhole spacetime or a charged Damour–Solodukhin wormhole spacetime as examples. …”

Star-forming Nuclear Clusters in Dwarf Galaxies Mimicking Active Galactic Nucleus Signatures in the Mid-infrared by Megan R. Sturm, Bayli Hayes, Amy E. Reines

“…Effectively finding and identifying active galactic nuclei (AGNs) in dwarf galaxies is an important step in studying black hole formation and evolution. In this work, we examine four mid-infrared (IR)-selected AGN candidates in dwarf galaxies with stellar masses between M _⋆  ~ 10 ^8 and 10 ^9 M _⊙ and find that the galaxies are host to nuclear star clusters (NSCs) that are notably rare in how young and massive they are. …”

Phase-transition-induced Collapse of Proto-compact Stars and Its Implication for Supernova Explosions by Xu-Run Huang, Shuai Zha, Ming-chung Chu, Evan P. O’Connor, Lie-Wen Chen

“…A small portion (∼0.04%−1%) of the released binding energy Δ E _B transforms into the diagnostic explosion energy E _exp,diag , which saturates at  ∼6 × 10 ^51 erg near the black hole formation. Note that our E _exp,diag represents an upper limit of the final explosion energies in realistic supernova simulations. …”
