Beyond Connection: Paradoxes of Psychedelic Resonance in Late Modernity
ABSTRACT This essay explores the enduring suspicion that psychedelic experiences are antithetical to the structural dynamic of modern societies through Hartmut Rosa's concepts of ‘resonance’ and ‘social acceleration’. Rosa's theoretical framework is particularly generative for studying the social meaning of contemporary psychedelia because it enables a

Suprathermal Electron Acceleration Comparison of the Venusian and Terrestrial Bow Shocks
Abstract We study suprathermal electron acceleration at the Venusian bow shock using the Parker Solar Probe gravity assists and the Venus Express spacecraft mission. The acceleration is classified by measuring the maximum energy and the power‐law spectral slope (index) of the electron phase space density immediately downstream of the shocks for ...

Van Allen Probes Observations of a Fundamental Poloidal Wave in the Plasmasphere
Abstract All past spacecraft observations of fundamental poloidal Alfvén (P1) waves attributed to ion drift resonance have been made outside the plasmasphere. In this study, we present the first spacecraft observations of a plasmaspheric P1 wave driven by that resonance.

Is Magnetic Reconnection Dominantly Spatially or Temporally Variable: First Results From TRACERS
Abstract The Tandem Reconnection And Cusp Electrodynamics Reconnaissance Satellites (TRACERS) small explorer mission was designed to: Determine whether magnetopause reconnection is primarily spatially or temporally variable for a range of solar wind conditions. Observations from the Analyzers for Cusp Ions (ACIs) on the two TRACERS spacecrafts are used

Reconnection Onset in Overstretched Thin Current Sheets: 3‐D Kinetic Picture
Abstract Evolution of the magnetotail equilibrium, whose current density iso‐contours are stretched beyond the magnetic field lines due to small ion anisotropy and agyrotropic effects on the scales of the thermal ion gyroradius (the so‐called overstretched thin current sheet) is considered using 3‐D explicit particle‐in‐cell simulations.

Abstract The Viking missions landed two spacecraft on Mars each equipped with a pyrolysis‐gas chromatograph‐mass spectrometer system capable of detecting signs of life. Although working as intended, detections of chloromethane and dichloromethane were initially attributed to terrestrial contamination.

General Relativistic Static Fluid Solutions with Cosmological Constant
This diploma thesis analyses static, spherically symmetric perfect fluid solutions to Einstein's field equations with cosmological constant. Constant density solutions are derived for different values of the cosmological constant.

Abstract Recent works suggest there are periods when the Sun encountered massive interstellar cold clouds which compressed the heliosphere to within Earth's orbit, exposing Earth to interstellar galactic cosmic rays and energetic particles of heliospheric origin.
