The Spitzer Warm Mission Science Prospects [PDF]

, 2007
After exhaustion of its cryogen, the Spitzer Space telescope will still have a fully functioning two-channel mid-IR camera that will have sensitivities better than any other ground or space-based telescopes until the launch of JWST.

Direct HST Dust Lane Detection in Powerful Narrow-Line Radio Galaxies

Frontiers in Astronomy and Space Sciences, 2017
We present the analysis of near-infrared Hubble Space Telescope imaging of 10 Fanaroff Riley II powerful radio galaxies at low redshift (0.03 < z < 0.11) optically classified as narrow-line radio galaxies.

Deep Spitzer/IRAC Data for z ∼ 10 Galaxies Reveal Blue Balmer Break Colors: Young Stellar Populations at ∼500 Myr of Cosmic Time

The Astrophysical Journal, 2023
We present the deepest constraints yet on the median rest-UV+optical spectral energy distribution (SED) of z ∼ 10 galaxies prior to James Webb Space Telescope science operations.

Proper motions of young stellar outflows in the mid-infrared with Spitzer II HH 377/Cep E

New Journal of Physics, 2014
We have used multiple mid-infrared observations at 4.5 μ m obtained with the infrared array camera, of the compact $(\sim 1.4^{\prime} )$ young stellar bipolar outflow Cep E to measure the proper motion of its brightest condensations.

A Review of Lightweight Design for Space Mirror Core Structure: Tradition and Future

Machines, 2022
With the continuous improvement of the imaging quality requirement of the space optical system, the large-aperture mirror becomes the research focus. However, the increase of the aperture will increase the whole weight which results in high launch cost ...

Miller and Urey in the Universe: detecting prebiotic molecules in star-forming regions

Revista Brasileira de Ensino de Física
Astronomical observations have revealed that the simple molecules used in the Miller and Urey experiments (H2O, CH4, NH3, and H2), along with methanol, carbon monoxide, and carbon dioxide, among many others, are abundant in solid form in molecular clouds
