On-orbit performance of the Spitzer Space Telescope: science meets engineering [PDF]

Journal of Astronomical Telescopes, Instruments, and Systems, 2022
The Spitzer Space Telescope operated for over 16 years in an Earth-trailing solar orbit, returning not only a wealth of scientific data but, as a by-product, spacecraft and instrument engineering data which will be of interest to future mission planners.

JWST Imaging of the Cartwheel Galaxy Reveals Dust Associated with SN 2021afdx

The Astrophysical Journal Letters, 2023
We present near- and mid-infrared (0.9–18 μ m) photometry of supernova (SN) 2021afdx, which was imaged serendipitously with the James Webb Space Telescope (JWST) as part of its Early Release Observations of the Cartwheel Galaxy.

Exploring the Distant Universe With the Spitzer Space Telescope [PDF]

AIP Conference Proceedings, 2004
The infrared Spitzer Space Telescope is the last of NASA’s Great Observatories. Highlights of the first results from the Infrared Spectrograph (IRS) Extragalactic Team are given. The main focus of this paper is a demonstration of the unprecedented sensitivity of the IRS, which makes observations of distant, dust enshrouded galaxies possible.

GOALS-JWST: Unveiling Dusty Compact Sources in the Merging Galaxy IIZw096

The Astrophysical Journal Letters, 2022
We have used the Mid-InfraRed Instrument (MIRI) on the James Webb Space Telescope (JWST) to obtain the first spatially resolved, mid-infrared images of IIZw096, a merging luminous infrared galaxy (LIRG) at z = 0.036.

Dust Disks Around Young Stellar Objects [PDF]

Journal of Astronomy and Space Sciences, 2016
To reproduce the spectral energy distributions (SEDs) of young stellar objects (YSOs), we perform radiative transfer model calculations for the circumstellar dust disks with various shapes and many dust species.

Spitzer Resurrector Mission: Advantages for Space Weather Research and Operations

Aerospace
In 1979, NASA established the Great Observatory program, which included four telescopes (Hubble, Compton, Chandra, and Spitzer) to explore the Universe.

Novel Deep Level Image State Ensemble Enhancement Method for M87 Imaging

Applied Sciences, 2020
Standard spatial domain filters fail to adequately denoise and enhance the contrast of an image. These filters have drawbacks like oversmoothing, diminished texture, and lack of generative capabilities.

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.

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.

CEERS Key Paper. V. Galaxies at 4 < z < 9 Are Bluer than They Appear–Characterizing Galaxy Stellar Populations from Rest-frame ∼1 μm Imaging

The Astrophysical Journal Letters, 2023
We present results from the Cosmic Evolution Early Release Survey on the stellar population parameters for 28 galaxies with redshifts 4 < z < 9 using imaging data from the James Webb Space Telescope (JWST) Mid-Infrared Instrument (MIRI) combined with ...
