PHOTOMETRIC MONITORING OF THE COLDEST KNOWN BROWN DWARF WITH THE SPITZER SPACE TELESCOPE [PDF]

, 2016
Because WISE J085510.83−071442.5 (hereafter WISE 0855-0714) is the coldest known brown dwarf (∼250 K) and one of the Sun’s closest neighbors (2.2 pc), it offers a unique opportunity to study a planet-like atmosphere in an unexplored regime of temperature.

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 ...

A HIDDEN POPULATION OF MASSIVE STARS WITH CIRCUMSTELLAR SHELLS DISCOVERED WITH THESPITZER SPACE TELESCOPE [PDF]

, 2010
We have discovered a large number of circular and elliptical shells at 24 μm around luminous central sources with MIPS on board the Spitzer Space Telescope.

Emergent Exoplanet Flux: Review of the Spitzer Results [PDF]

, 2008
Observations using the Spitzer Space Telescope provided the first detections of photons from extrasolar planets. Spitzer observations are allowing us to infer the temperature structure, composition, and dynamics of exoplanet atmospheres.

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.

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.

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.

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.
