COSMOS: Hubble Space Telescope Observations [PDF]

The Astrophysical Journal Supplement Series, 2007
The Cosmic Evolution Survey (COSMOS) was initiated with an extensive allocation (590 orbits in Cycles 12-13) using the Hubble Space Telescope (HST) for high resolution imaging. Here we review the characteristics of the HST imaging with the Advanced Camera for Surveys (ACS) and parallel observations with NICMOS and WFPC2.

MEASURING THE HUBBLE CONSTANT WITH THE HUBBLE SPACE TELESCOPE [PDF]

Proceedings of the International Astronomical Union, 1995
AbstractTen years ago our team completed the Hubble Space Telescope Key Project on the extragalactic distance scale. Cepheids were detected in some 25 galaxies and used to calibrate four secondary distance indicators that reach out into the expansion field beyond the noise of galaxy peculiar velocities.

Maximum Entropy Estimates of Hubble Constant from Planck Measurements [PDF]

Entropy
A maximum entropy (ME) methodology was used to infer the Hubble constant from the temperature anisotropies in cosmic microwave background (CMB) measurements, as measured by the Planck satellite.

AT2025ulz and S250818k: Zooming in with the Hubble Space Telescope

The Astrophysical Journal Letters
AT2025ulz is an optical/near-infrared transient discovered during follow-up of the candidate gravitational wave (GW) event S250818k. Its young age (≲1 day), rapid decline, and strong color evolution over the first 48 hr classify it as a potential ...

Constraint on the equation of state parameter (ω) in non-minimally coupled f(Q) gravity

Physics Letters B, 2021
We study observational constraints on the modified symmetric teleparallel gravity, the non-metricity f(Q) gravity, which reproduces background expansion of the universe.

HST Low-resolution Stellar Library

The Astrophysical Journal Supplement Series, 2023
In order to provide fundamental stellar spectra that extend into the UV, Hubble Space Telescope’s Space Telescope Imaging Spectrograph targeted 556 stars via proposals GO9088, GO9786, GO10222, and GO13776.

The Hubble Space Telescope [PDF]

International Astronomical Union Colloquium, 1990
AbstractThe Hubble Space Telescope was launched from the Kennedy Space Center on April 24, 1990. Its initial check-out indicates that all sub-systems of the satellite are working very well, with two key exceptions: The line-of-sight pointing is subject to occasional jitter apparently induced by thermal stresses in the solar arrays; this is expected to ...

What the Upper Atmospheres of Giant Planets Reveal

Remote Sensing, 2022
The upper atmospheres of the Giant Planets, Jupiter, Saturn, Uranus and Neptune are transition regions between meteorological layers and outer space. As a result of their exceptionally rarefied nature, they are highly sensitive and therefore revealing ...

First Results from a Panchromatic HST/WFC3 Imaging Study of the Young, Rapidly Evolving Planetary Nebulae NGC 7027 and NGC 6302

Galaxies, 2020
We present the first results from comprehensive, near-UV-to-near-IR Hubble Space Telescope Wide Field Camera 3 (WFC3) emission-line imaging studies of two young planetary nebulae (PNe), NGC 7027 and NGC 6302.
