The star formation history of the Hubble sequence: spatially resolved colour distributions of intermediate-redshift galaxies in the Hubble Deep Field [PDF]

, 1998
We analyse the spatially resolved colours of distant galaxies of known redshift in the Hubble Deep Field, using a new technique based on matching resolved four-band colour data to the predictions of evolutionary synthesis models.

A Long‐Term Study of Jupiter's Equatorial Winds at the Top of the Troposphere

Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.
Abstract Jupiter's equatorial atmosphere is covered by dense hazes that extend from the main cloud level to the lower stratosphere. These hazes are variable in optical depth and brightness, although the causes of these variations are unknown. James Webb Space Telescope (JWST) observations of the equatorial hazes in 2022 in near‐infrared wavelengths ...

Spitzer 70-micron Confusion Level [PDF]

, 2008
Spitzer 70μm confusion measurements are presented based on ultra-deep MIPS-70μm observations of GOODS Hubble Deep Field North (HDFN). The instrument noise for the MIPS-70μm band integrates down with nearly t^(−0.5) for the low background HDF-N field. The

Climate Emergency and Different Ways to Fail? The Fermi Paradox, the Simulation Hypothesis, Agency and Hope

Journal for the Theory of Social Behaviour, Volume 55, Issue 4, December 2025.
ABSTRACT Humanity seems stuck on different ways to fail to meet the challenge posed by a declared climate emergency and manifest problems of ecological breakdown. Rather than reprise these failures, we use the Fermi Paradox and simulation hypothesis to make a simple point about agency. The argument unfolds in two sections.

The Leakage of Lyman-continuum Photons from a Major Merger at z ∼ 1

The Astrophysical Journal
We report the detection of Lyman-continuum (LyC) photons from a massive interacting system at z = 1.097 in the Hubble Ultra Deep Field. The LyC detection is made in the far-ultraviolet F154W band of the UVIT telescope on board AstroSat.

THE 2012 HUBBLE ULTRA DEEP FIELD (UDF12): OBSERVATIONAL OVERVIEW [PDF]

The Astrophysical Journal Supplement Series, 2013
We present the 2012 Hubble Ultra Deep Field campaign (UDF12), a large 128-orbit Cycle 19 \HST\ program aimed at extending previous WFC3/IR observations of the UDF by quadrupling the exposure time in the F105W filter, imaging in an additional F140W filter, and extending the F160W exposure time by 50%.

Keck Spectroscopy of Objects with Lens-like Morphologies in the Hubble Deep Field [PDF]

, 1996
We present spectroscopy from the Keck telescope of three sets of objects in the Hubble Deep Field (HDF) that have lens-like morphologies. In the case of J123641+621204, which is composed of four objects with similar colors and a mean separation of ≲0.″8,

Probing Jupiter's Atmosphere Through Juno Radio Occultations: Analysis of the Atmospheric Thermal Structure

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract The upper layers of Jupiter's atmosphere, offering critical insights into the planet's deeper structure, are accessible through radio occultation experiments. Since July 2023, NASA's Juno extended mission has provided the first high‐resolution radio occultation measurements since the Voyager era, probing the thermal structure and composition ...

Caltech Faint Galaxy Redshift Survey. XIV. Galaxy Morphology in the Hubble Deep Field (North) and Its Flanking Fields to z = 1.2 [PDF]

, 2000
Morphological classifications are reported for Hubble Space Telescope images of 241 galaxies in the Hubble Deep Field and its flanking fields with measured redshifts in the interval 0.25 < z < 1.2, drawn from a magnitude-limited redshift survey to R = 24.
