Terrestrial Analogs to Titan for Geophysical Research

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

The Dynamics of the Dwarf Elliptical Galaxy FS 76: Bridging the Kinematic Dichotomy between Elliptical and Dwarf Elliptical Galaxies [PDF]

open access: yesThe Astrophysical Journal, 2001
We present major- and minor-axis kinematics out to ˜2 half-light radii for the bright (MB = -16.7) dwarf elliptical galaxy (dE) FS 76, a member of the NGC 5044 group. Its velocity dispersion is 46 ‘ 2 km s-1 in the center and rises to 70 ‘ 10 km s-1 at half-light radius. Beyond 1Re, the dispersion starts to fall again.

Autoparallels and the Inverse Problem of the Calculus of Variations

open access: yesFortschritte der Physik, Volume 74, Issue 5, May 2026.
ABSTRACT We prove that autoparallel curves associated with a torsion‐free but not necessarily metric‐compatible affine connection can be derived from an action principle. We explicitly construct the action functional and show by standard variational techniques that it produces the desired equations.

A Possible Solution to the Mystery of the ANITA Anomalous Events

open access: yesAnnalen der Physik, Volume 538, Issue 4, April 2026.
In 2006 and 2014, the Antarctic Impulsive Transient Antenna (ANITA), a balloon‐borne radio observatory flying over Antarctica, detected two strange upward‐going radio pulse events that have not yet been explained by our current understanding of physics.

Extended stellar kinematics of elliptical galaxies in the Fornax cluster?;?? [PDF]

open access: yes, 1998
. We present extended stellar kinematics for a sample of elliptical galaxies in the Fornax cluster. Out of the 13 galaxies presented here, ve (FCC 119, FCC 136, NGC 1373, NGC 1428, FCC 335) have no pre-viously published kinematical data.

The Dynamics of White Dwarfs, Black Holes and Stellar Cusps [PDF]

open access: yes, 2013
This thesis contains topics related mostly to the dynamics of white dwarfs (chapter 2), the dynamics of stars around binary super massive black holes (chapters 4, 5 and 6) and dynamics in the singular isothermal sphere (chapter 7).

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

open access: yesFortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Simulating molecular cloud regulated star formation in Galaxies [PDF]

open access: yes, 2007
This thesis is primarily concerned with understanding the process of galaxy formation via the simulation of the interstellar medium, star formation and supernova feedback.
