The present paper proposes a model that captures some salient features of the dynamical evolution of this stream. In particular, they find that the stream circularizes through the dissipative effects of self-collisions and identify a parameter that characterizes two distinct regimes, fast and slow, of the circularization.

Nonradial neutrino emission upon black hole formation in core collapse supernovae
Jia-Shian Wang,Jeff Tseng,Samuel Gullin和Evan P. O’Connor
理论物理。启维104, 104030 (2021) – Published 12 November 2021

Core-collapse supernovae resulting in black hole formation are expected to feature a precipitous decline in neutrino luminosity. The authors provide considerable nuance to this picture by considering non-radial neutrino emission in both the spherically symmetric (Schwarzschild) and rotating (Kerr) black hole cases. In each of these cases, they show that non-radial neutrinos affect the luminosity cut-off shape in interesting ways that indicate a rich domain for further theoretical and observational exploration.

Gravity interpretation for the Bethe Ansatz expansion of the N = 4 符号索引
Ofer Aharony, Francesco Benini, Ohad Mamroud, and Paolo Milan
理论物理。启维104, 086026 (2021) – Published 21 October 2021

The superconformal index of the maximally supersymmetric SU(N) Yang-Mills theory can be expressed as a sum over solutions to Bethe Ansatz Equations. Within the AdS/CFT framework, the authors find a one-to-one mapping of such solutions, which have good large N limit, to (complex) Euclidean black hole solutions on the gravity side. This mapping captures both the leading contribution from the classical gravity action and non-perturbative corrections.

In this paper, the authors introduce a new way to measure the Hubble constant purely from gravitational wave data, using the binary Love relations, which govern the tidal deformability of neutron stars in an EOS insensitive way. The authors use both real and synthetic data to implement their program and predict an improvement to less than 10 percent accuracy for data from third generation gravitational wave detectors.

New insights into the formation and growth of boson stars in dark matter halos
Jiajun Chen, Xiaolong Du, Erik W. Lentz, David J. E. Marsh, and Jens C. Niemeyer
理论物理。启维104, 083022 (2021) – Published 14 October 2021

This paper studies the formation and growth of boson stars via gravitational condensation, using non-linear numerical techniques, incorporating, for the first time, fully dynamical repulsive and attractive self-interactions. For strong attraction, the boson star becomes unstable and ultimately breaks up for very strong coupling. Repulsion encourages boson star formation, whilst, in the case of pure gravity, the growth of boson stars in haloes slows down as per expectations.

的身份验证ors find constrained instantons – configurations that extremize the action subject to a constraint – in Einstein gravity with and without a cosmological constant. Such instantons are expected to contribute to non-perturbative processes in quantum gravity. With negative cosmological constant, these configurations describe wormholes connecting two asymptotic regions.

Can small-scale baryon inhomogeneities resolve the Hubble tension? An investigation with ACT DR4

理论物理。启维104, 063535 (2021) – Published 21 September 2021

的身份验证ors analyze an appealing attempt to resolve the Hubble tension that modifies the physics around the time of recombination by small-scale baryon density inhomogeneities (e.g. by primordial magnetic fields). Using the most recent data of the Atacama Cosmology Telescope (ACT), they find that baryon clumping on the CMB is severely constrained such that this mechanism most likely does not solve the Hubble tension. However, a time-dependent version of that scenario could evade these strong constraints.

This is the third paper in an extended study (see Phys. Rev. D 102, 103530 and Phys. Rev. D 103, 123550) of the impact of galaxy bias modeling on the extraction of cosmological parameters from the large scale structure. Galaxy bias describes the possibility that galaxies do not faithfully trace the distribution of mass in the Universe and the modeling of this relationship. The authors comprehensively study the goodness and range of validity of different bias models that go beyond the leading order by testing them against different simulated galaxy samples that have the clustering properties of several real galaxy data catalogs. This is an important contribution to a decisive aspect of future observational large scale structure programs.
