Spatial and Energy Dependence of Energetic Electron Precipitation Originating From Jupiter's Inner and Middle Magnetosphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract Energetic electron precipitation transfers trapped magnetospheric energy into Jupiter's atmosphere, yet its contribution beyond the main auroral oval has to be fully quantified. This study statistically investigates the atmospheric energy input from electrons in the 30 keV–1.2 MeV range using in situ measurements from the Juno spacecraft ...

Trans-Neptunian Objects with Hubble Space Telescope ACS/WFC [PDF]

, 2010
We introduce a novel search technique that can identify trans-neptunian objects in three to five exposures of a pointing within a single Hubble Space Telescope orbit. The process is fast enough to allow the discovery of candidates soon after the data are

Hubble Space Telescope Observations of the Interstellar Interloper 3I/ATLAS

The Astrophysical Journal Letters
We present high-angular-resolution observations of the third known interstellar interloper, 3I/ATLAS, from the Hubble Space Telescope. The object is clearly active at 3.8 au preperihelion, showing dust emitted from the hot, Sun-facing side of the nucleus

The cosmological ultra-low frequency radio background: a solution to the Hubble tension and the 21-cm excess trough

European Physical Journal C: Particles and Fields, 2023
Recent observations of the Cosmic Microwave Background and the Hubble Space Telescope obtain two different values of the Hubble constant with a discrepancy of at least $$4.4 \sigma $$ 4.4 σ , which is now known as the Hubble tension.

Motional Induction in Ganymede's Ocean

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract We investigate the magnetic signature of oceanic circulation in Ganymede's subsurface ocean using kinematic induction modeling. Our approach couples zonal jet flows from rotating thermal convection simulations with magnetic field models incorporating Ganymede's internal dynamo and external contributions from Jupiter.

H_0 and Odds on Cosmology [PDF]

, 1995
Recent observations by the Hubble Space Telescope of Cepheids in the Virgo cluster imply a Hubble Constant $H_0=80\pm17$\ km/sec/Mpc. We attempt to clarify some issues of interpretation of these results for determining the global cosmological parameters $

LensWatch. I. Resolved HST Observations and Constraints on the Strongly Lensed Type Ia Supernova 2022qmx (“SN Zwicky”)

The Astrophysical Journal, 2023
Supernovae (SNe) that have been multiply imaged by gravitational lensing are rare and powerful probes for cosmology. Each detection is an opportunity to develop the critical tools and methodologies needed as the sample of lensed SNe increases by orders ...

Auroral Emissions on Ganymede: New Constraints on Their Electron Energy Dependence

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Auroral emissions on Ganymede provide critical insights into its magnetospheric dynamics and atmospheric composition. Using a physics‐based atmospheric model with recent atmospheric observations and laboratory measurements of electron‐impact cross‐sections, this study revisits and significantly refines the relationship between auroral emission

Harnessing the Hubble Space Telescope Archives: A Catalog of 21,926 Interacting Galaxies

The Astrophysical Journal, 2023
Mergers play a complex role in galaxy formation and evolution. Continuing to improve our understanding of these systems requires ever larger samples, which can be difficult (even impossible) to select from individual surveys.
