Where Galaxies Go to Die: The Environments of Massive Quiescent Galaxies at 3 < z < 5

Ian McConachie, Anna de Graaff, Michael V. Maseda, Joel Leja et al. • The Astrophysical Journal (2026)

At low redshift, massive quiescent galaxies (MQGs) are most frequently found in massive, rich galaxy clusters, but at high redshift the trend is less clear. Here, we present spectroscopic evidence of the effects of environment on the format...

Intergalactic Wandering Stars in the Local Universe: Theoretical Predictions for Their Distance and Luminosity Distribution

Jia-Hui Wang, Maosheng Xiang, Ji-Feng Liu • The Astrophysical Journal (2025)

Intergalactic wandering stars (IWSs) within 10 Mpc remain a poorly explored area of astronomy. Such stars, if they exist, are supposed to be wandering objects as they are not bound by the gravitational potential of any galaxy. We set out to...

Anti-de Sitter → de Sitter transition driven by Casimir forces and mitigating tensions in cosmological parameters

Luis A. Anchordoqui, Ignatios Antoniadis, Dieter Lüst • Physics Letters B (2024)

Over the last few years, low- and high-redshift observations set off tensions in the measurement of the present-day expansion rate H0 and in the determination of the amplitude of the matter clustering in the late Universe (parameterized by ...

An Investigation of Disk Thickness in M51 from Hα, Paα, and Mid-infrared Power Spectra

Bruce G. Elmegreen, Daniela Calzetti, Angela Adamo, Karin Sandstrom et al. • The Astrophysical Journal (2025)

Power spectra (PS) of high-resolution images of M51 (NGC 5194) taken with the Hubble Space Telescope and the James Webb Space Telescope (JWST) have been examined for evidence of disk thickness in the form of a change in slope between large ...

On the Formation of Retrograde S-type Planets in Binaries with a Polar Circumbinary Disk

Cheng Chen, Philip J. Armitage, C. J. Nixon, Stephen H. Lubow et al. • The Astrophysical Journal Letters (2026)

Retrograde S-type planets have been observed in several binary systems, yet their formation pathway remains poorly understood. With high-resolution hydrodynamic simulations, we demonstrate that a polar circumbinary disk around an eccentric,...

WORKPLANS: Workshop on Planetary Nebula Observations

Isabel Aleman, Jeronimo Bernard-Salas, Joel H. Kastner, Toshiya Ueta et al. • Galaxies (2020)

This workshop is the second of the WORKPLANS series, which we started in 2016. The main goal of WORKPLANS is to build up a network of planetary nebulae (PNe) experts to address the main open questions in the field of PNe research. The speci...

Smoothed Particle Hydrodynamics in Astrophysics

Volker Springel • Annual Review of Astronomy and Astrophysics (2010)

This review discusses smoothed particle hydrodynamics (SPH) in the astrophysical context, with a focus on inviscid gas dynamics. The particle-based SPH technique allows an intuitive and simple formulation of hydrodynamics that has excellent...

The Role of Mixing in Astrophysics

D. Arnett • The Astrophysical Journal Supplement Series (2000)

The role of hydrodynamic mixing in astrophysics is reviewed, emphasizing its connections with laser physics experiments and inertial confinement fusion. Computer technology now allows us to use two-dimensional simulations, with complex micr...

Nuclear structure and astrophysics

Hubert Grawe, Karlheinz Langanke, Gabriel Martínez-Pinedo • Reports on Progress in Physics (2007)

The nuclear structure in regions of the Segré chart which are of astrophysical importance is reviewed. The main emphasis is put on those nuclei that are relevant for stellar nucleosynthesis in fusion processes, and in slow neutron capture, ...
