Exploring the gravitationally lensed system HE 1104-1805: Near-IR Spectroscopy [PDF]

open access: yes, 2000
(Abridged) A new technique for the spatial deconvolution of spectra is applied to near-IR (0.95 - 2.50 micron) NTT/SOFI spectra of the lensed, radio-quiet quasar HE 1104-1805. The continuum of the lensing galaxy is revealed between 1.5 and 2.5 micron. It

Spatially Resolved Spectroscopy of Starburst and Post-Starburst Galaxies in The Rich z~0.55 Cluster CL0016+16

open access: yes, 2010
We have used the Low Resolution Imaging Spectrograph (LRIS) on the W.M. Keck I telescope to obtain spatially resolved spectroscopy of a small sample of six post-starburst and three dusty-starburst galaxies in the rich cluster CL0016+16 at z=0.55.

Deep‐Ultraviolet (DUV) Raman and Fluorescence of Perchlorates and Chlorates: Implications for the Detection of Oxychlorines by the SHERLOC Instrument in Jezero Crater, Mars

open access: yesEarth and Space Science, Volume 13, Issue 1, January 2026.
Abstract Oxychlorines (i.e., perchlorates (ClO4−) and chlorates (ClO3−)) have been detected by several landed missions on Mars at various locations. These missions have provided crucial information about the geographic distribution and abundances of oxychlorines on Mars but have not definitively identified the cation and anion type of in situ, solid ...

Short‐Term Effect of Mars‐Like Radiation on Carbon and Oxygen Isotope Compositions of Carbonates

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract The stable isotope composition of carbonates records the environmental formation conditions and can indicate potential biosignatures if formed biologically. Martian meteorite carbonates display unusually high δ13C values, not explained using known terrestrial processes.

Heavy Metal Contamination in Chocolates and Candies: Sources, Health Risks, and Analytical Insights

open access: yesJournal of Chemistry, Volume 2026, Issue 1, 2026.
The presence of heavy metals in chocolates and candies poses growing public health concerns, particularly for children who are frequent consumers. This review consolidates evidence on the occurrence, sources, toxicological impacts, and analytical monitoring of metals, including Pb, Cd, Hg, As, Cr, Ni, and Al, in confectionery products.

Magellan Spectroscopy of Active Galactic Nuclei in Low-mass Galaxies: Scaling Relations and a Triple-peaked Active Galactic Nucleus

open access: yesThe Astrophysical Journal
In this work, we aim to further populate the low-mass regime of black hole (BH) scaling relations to better understand the formation and growth mechanisms of central supermassive BHs. We target six galaxies that have been previously identified as hosting

Nature of a Strongly-Lensed Submillimeter Galaxy SMM J14011+0252

open access: yes, 2004
We have carried out near-infrared JHK spectroscopy of a gravitationally lensed submillimeter galaxy SMM J14011+0252 at z=2.565, using OHS and CISCO on the Subaru telescope.
