A Spitzer Space Telescope Infrared Spectrograph Survey of Warm Molecular Hydrogen in Ultraluminous Infrared Galaxies [PDF]

, 2006
We have conducted a survey of ultraluminous infrared galaxies (ULIRGs) with the Infrared Spectrograph on the Spitzer Space Telescope, obtaining spectra from 5.0 to 38.5 μm for 77 sources with 0.02 < z < 0.93.

Near to Mid-infrared Spectroscopy of (65803) Didymos as Observed by JWST: Characterization Observations Supporting the Double Asteroid Redirection Test

The Planetary Science Journal, 2023
The Didymos binary asteroid was the target of the Double Asteroid Redirection Test (DART) mission, which intentionally impacted Dimorphos, the smaller member of the binary system.

Spitzer Space Telescope Observations of Kepler’s Supernova Remnant: A Detailed Look at the Circumstellar Dust Component [PDF]

, 2007
We present 3.6-160 μm infrared images of Kepler's supernova remnant (SN 1604) obtained with the IRAC and MIPS instruments on the Spitzer Space Telescope. We also present MIPS SED low-resolution spectra in the 55-95 μm region. The observed emission in the

Refining the Transit-timing and Photometric Analysis of TRAPPIST-1: Masses, Radii, Densities, Dynamics, and Ephemerides

The Planetary Science Journal, 2021
We have collected transit times for the TRAPPIST-1 system with the Spitzer Space Telescope over four years. We add to these ground-based, HST, and K2 transit-time measurements, and revisit an N -body dynamical analysis of the seven-planet system using ...

The 24 Micron Source Counts in Deep Spitzer Space Telescope Surveys [PDF]

, 2004
Galaxy source counts in the infrared provide strong constraints on the evolution of the bolometric energy output from distant galaxy populations. We present the results from deep 24 μm imaging from Spitzer surveys, which include ≈5 × 104 sources to an 80%

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.

Large Cold Dust Reservoir Revealed in Transitional SN Ib 2014C by James Webb Space Telescope Mid-infrared Spectroscopy

The Astrophysical Journal
Supernova (SN) 2014C is a rare transitional event that exploded as a hydrogen-poor, helium-rich Type Ib SN and subsequently interacted with a hydrogen-rich circumstellar medium (CSM) a few months postexplosion.

Spitzer Space Telescope spectra of post-AGB stars in the large magellanic Cloud - polycyclic aromatic hydrocarbons at low metallicities [PDF]

, 2014
This paper reports variations of polycyclic aromatic hydrocarbons (PAHs) features that were found in Spitzer Space Telescope spectra of carbon-rich post-asymptotic giant branch (post-AGB) stars in the Large Magellanic Cloud (LMC).

Prominent Mid-infrared Excess of the Dwarf Planet (136472) Makemake Discovered by JWST/MIRI Indicates Ongoing Activity

The Astrophysical Journal Letters
We report on the discovery of a very prominent mid-infrared (18–25 μ m) excess associated with the trans-Neptunian dwarf planet (136472) Makemake. The excess, detected by the Mid-Infrared Instrument of the James Webb Space Telescope, along with previous ...
