Heavy Elements and Electromagnetic Transients from Neutron Star Mergers

open access: yesAnnalen der Physik, Volume 536, Issue 2, February 2024.
Astro‐(physics) has made major leaps forward through the combined information provided by both gravitational waves and electromagnetic emission from the first detected neutron star merger event. This review provides an up‐to‐date overview of today's understanding of neutron star mergers and their electromagnetic emission and it discusses possible ...

Dust in External Galaxies [PDF]

open access: yes, 2009
Existing (Spitzer Space Telescope) and upcoming (Herschel Space Telescope) facilities are deepening our understanding of the role of dust in tracing the energy budget and chemical evolution of galaxies.

MIR Spectra and Analysis of Jovian Trojan Asteroids

open access: yesThe Planetary Science Journal, 2023
Jovian Trojan asteroids make up a large group of primitive bodies that populate Jupiter's L4 and L5 Lagrange points. The Trojans’ dynamics and composition carry insight into the formation mechanisms that shaped our solar system. Mid-infrared (MIR; 5–35 μ

Stability of the Infrared Array Camera for the Spitzer Space Telescope [PDF]

open access: yesSPIE Proceedings, 2008
We present an analysis of the stability of the Infrared Array Camera (IRAC) on board the Spitzer Space Telescope over the first 4.5 years of in-flight operations. IRAC consists of two InSb and two Si:As 256x256 imaging arrays with passbands centered on 3.6, 4.5. 5.8 and 8.0 microns.

Optical and Mid-Infrared Observations of the Planetary Nebula NGC 6781

open access: yes, 2011
Although the planetary nebula NGC 6781 appears to possess an elliptical morphology, its kinematic and emission characteristics are in many ways unusual, and it is possible that it may represent a bipolar source oriented close to the line of sight.

The galactic first-look survey with the Spitzer space telescope [PDF]

open access: yesAdvances in Space Research, 2005
The galactic first look survey (GFLS) of the Spitzer space telescope was executed during 1–11 December 2003 as one of the first science observations during nominal operations. The aim of the FLS is to provide a characteristic “first-look” at the mid-and far-infrared sky at sensitivities that allow the detection of point sources ≈100 times fainter than ...

Atmospheric Chemistry of Venus-like Exoplanets

open access: yes, 2010
We use thermodynamic calculations to model atmospheric chemistry on terrestrial exoplanets that are hot enough for chemical equilibira between the atmosphere and lithosphere, as on Venus. The results of our calculations place constraints on abundances of

Infrared Fluxes and Lightcurves of Near-Earth Objects: The Full Spitzer Sample

open access: yesThe Astronomical Journal
The IRAC camera on the Spitzer Space Telescope observed 2175 near-Earth objects (NEOs) during its Warm Mission phase, primarily in three large surveys, and also in a small number of a dedicated projects.

Spitzer Space Telescope Infrared Imaging and Spectroscopy of the Crab Nebula [PDF]

open access: yes, 2006
We present 3.6, 4.5, 5.8, 8.0, 24, and 70 micron images of the Crab Nebula obtained with the Spitzer Space Telescope IRAC and MIPS cameras, Low- and High-resolution Spitzer IRS spectra of selected positions within the nebula, and a near-infrared ground ...

KMT-2018-BLG-0029Lb and OGLE-2019-BLG-0960Lb: Mass Measurements for Two Super-Earth Microlensing Planets

open access: yesThe Astronomical Journal
KMT-2018-BLG-0029Lb and OGLE-2019-BLG-0960Lb were the lowest mass-ratio microlensing planets at the time of discovery. For both events, microlensing parallax measurements from the Spitzer Space Telescope implied lens systems that were more distant and ...
