The Hubble Deep Hydrogen Alpha (HDHα) Project. I. Catalog of Emission-line Galaxies

The Astrophysical Journal Supplement Series
We present the first results of the Hubble Deep Hydrogen Alpha (HDH α ) project, which analyzes the space-borne deep H α narrowband imaging data in the GOODS-S region. The HDH α data comprises 72 orbits’ images taken with the Hubble Space Telescope (HST)

QSOs and Absorption Line Systems Surrounding the Hubble Deep Field [PDF]

, 2000
We have imaged a 45x45 sq. arcmin. area centered on the Hubble Deep Field (HDF) in UBVRI passbands, down to respective limiting magnitudes of approximately 21.5, 22.5, 22.2, 22.2, and 21.2.

Detection of Strong Clustering of Red K-selected Galaxies at 2 < zphot < 4 in the Hubble Deep Field-South [PDF]

, 2003
The clustering properties of faint KVega < 24 galaxies are measured in ultradeep J, H, and K near-IR images of the Hubble Deep Field-South (HDF-S), obtained with ISAAC at the Very Large Telescope.

The Cycles and Dynamical Properties of Convective Outbreaks in Jupiter's Highest Speed Jet From a 55‐Year Study

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Jupiter's most intense jet at planetographic latitude 23.7°N experiences vigorous planetary‐scale disturbances. The onset consists of the outbreak of 1–3 bright clouds of convective origin developing turbulent plumes. Observed events between 1970 and 2025 shows a cycle of activity with a period in the range of 3.8–5.1 yrs interrupted between ...

The Properties of Microjansky Radio Sources in the Hubble Deep Field-North, SSA 13, and SSA 22 Fields [PDF]

, 2002
We present multiwavelength observations for a large sample of microjansky radio sources detected in ultradeep 1.4 GHz maps centered on the Hubble Deep Field-North (HDF-N) and the Hawaii Survey Fields SSA 13 and SSA 22. Our spectroscopic redshifts for 169

Logarithmic and Strong Coupling Models in Weyl‐Type f(Q,T)$f(Q,T)$ Gravity

Annalen der Physik, Volume 538, Issue 1, January 2026.
This work explores Weyl‐type f(Q,T) gravity using recent observational datasets — CC, Pantheon+, Union 3.0, and DESI DR2. Through MCMC analysis of logarithmic and strong coupling models, the study reveals a transition from deceleration to acceleration, quintessence‐to‐phantom dynamics, and late‐time consistency with LCDM, offering a geometry‐driven ...

The Hubble Deep Field in the Far Ultraviolet

, 2001
Results from a recent HST survey of field galaxies at wavelengths 1600 Angstroms and 2400 Angstroms are be presented. The data are used to constrain the fraction of Lyman-continuum radiation that escapes from galaxies at redshifts z ~ 1.

A z=5.34 Galaxy Pair in the Hubble Deep Field [PDF]

, 1998
We present spectrograms of the faint V-drop (V(606) = 28.1, I(814) = 25.6) galaxy pair HDF3-951.1 and HDF3-951.2 obtained at the Keck II Telescope. Fernandez-Soto, Lanzetta, & Yahil (1998) derive a photometric redshift of z(ph) = 5.28 (+0.34,-0.41; 2 ...

Barred Galaxies at z > 0.7: NICMOS Hubble Deep Field-North Observations [PDF]

, 2003
Previous optical studies found an unexpected deficit of bars at z > 0.7. To investigate the effects of band shifting, we have studied the fraction of barred spiral galaxies in the Near-Infrared Camera and Multi-Object Spectrometer (NICMOS) Hubble Deep ...

Structure of Jupiter's High‐Latitude Storms: Folded Filamentary Regions Revealed by Juno

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Sprawling, turbulent cloud formations dominate the meteorology of Jupiter's mid‐to‐high latitudes, known as Folded Filamentary Regions (FFRs). A multi‐wavelength characterization by Juno reveals the spatial distribution, vertical structure, and energetics of the FFRs.
