CEERS Key Paper. VII. JWST/MIRI Reveals a Faint Population of Galaxies at Cosmic Noon Unseen by Spitzer
The Cosmic Evolution Early Release Science program observed the Extended Groth Strip (EGS) with the Mid-Infrared Instrument (MIRI) on the James Webb Space Telescope (JWST) in 2022. In this paper, we discuss the four MIRI pointings that observed with longer ...
Bristol2023Finite-resolution Deconvolution of Multiwavelength Imaging of 20,000 Galaxies in the COSMOS Field: The Evolution of Clumpy Galaxies over Cosmic Time
Compact star-forming clumps observed in distant galaxies are often suggested to play a crucial role in galaxy assembly. In this paper, we use a novel approach of applying finite-resolution deconvolution on ground-based images of the COSMOS field to resolve ...
IOP Publishing Ltd2022A Microlensing Accretion Disk Size Measurement in the Lensed Quasar WFI 2026-4536
Frédéric Courbin, Martin Raoul Robert Millon, Vivien François Bonvin
We use 13 seasons of R-band photometry from the 1.2 m Leonard Euler Swiss Telescope at La Silla to examine microlensing variability in the quadruply imaged lensed quasar WFI 2026-4536. The lightcurves exhibit similar to 0.2 mag of uncorrelated variability ...
IOP PUBLISHING LTD2020The Gaia-ESO Survey: dynamics of ionized and neutral gas in the Lagoon nebula (M 8)
Aims. We present a spectroscopic study of the dynamics of the ionized and neutral gas throughout the Lagoon nebula (M 8), using VLT-FLAMES data from the Gaia-ESO Survey. The new data permit exploration of the physical connections between the nebular gas an ...
Edp Sciences S A2017Extreme Deuterium Excesses in Ultracarbonaceous Micrometeorites from Central Antarctic Snow
Anders Meibom, François Robert
Primitive interplanetary dust is expected to contain the earliest solar system components, including minerals and organic matter. We have recovered, from central Antarctic snow, ultracarbonaceous micrometeorites whose organic matter contains extreme deuter ...
2010Proto-Planetary Disk Chemistry Recorded By D-Rich Organic Radicals In Carbonaceous Chondrites
Anders Meibom, François Robert
Insoluble organic matter (IOM) in primitive carbonaceous meteorites has preserved its chemical composition and isotopic heterogeneity since the solar system formed similar to 4.567 billion years ago. We have identified the carrier moieties of isotopically ...
2009The origin of short-lived radionuclides and the astrophysical environment of solar system formation
Based on early solar system abundances of short-lived radionuclides (SRs), such as Al-26 (T-1/2 = 0.74 Myr) and Fe-60 (T-1/2 1.5 Myr), it is often asserted that the Sun was born in a large stellar cluster, where a massive star contaminated the protoplaneta ...
2008The oxygen isotopic composition of the Sun as a test of the supernova origin of Al-26 and Ca-41
Short-lived radionuclides were present in the solar protoplanetary disk in abundances much higher than in the ambient interstellar medium and require a last minute origin. Al-26 (T-1/2 = 0.73 Myr) and Ca-41 (T-1/2 = 0.1 Myr) abundances in the protoplanetar ...
2007Report - Mineralogy and petrology of comet 81P/Wild 2 nucleus samples
Anders Meibom, Philippe Gillet, François Robert
The bulk of the comet 81P/Wild 2 ( hereafter Wild 2) samples returned to Earth by the Stardust spacecraft appear to be weakly constructed mixtures of nanometer-scale grains, with occasional much larger ( over 1 micrometer) ferromagnesian silicates, Fe-Ni s ...
2006Young chondrules in CB chondrites from a giant impact in the early Solar System
Chondrules, which are the major constituent of chondritic meteorites, are believed to have formed during brief, localized, repetitive melting of dust ( probably caused by shock waves(1,2)) in the protoplanetary disk around the early Sun. The ages of primit ...
