ABSTRACT Absorption-selected galaxies offer an effective way to study low-mass at high redshift. However, the physical properties of underlying galaxy population remain uncertain. In particular, multiphase circumgalactic medium is thought hold key information on gas flows into and out that are vital for evolution models. Here, we present ALMA observations CO molecular in host H2-bearing absorbe...

We report a λ > ∼ 1 cm search for rotational molecular absorption towards quasars, now possible with the upgraded Australia Telescope Compact Array (ATCA). The targets were PKS 0201+113, PKS 0336–017 and Q 0537–286, where known damped Lyman-alpha absorption systems (DLAs) could cause redshifted molecular absorption in the 12 mm band of the telescope. We place 3σ upper limits on any HCO 0 → 1 ab...

Our observations with the ISO SWS revealed that H2O band at 2.7μm appears as absorption already in an M2 giant β Peg and strengthens towards later M giants. Further, CO2 4.2μm band appears as absorption in an M7 giant SWVir and especially strong in a Mira variable SVir. The excitation temperatures of these molecular bands estimated from their band shapes turn out to be 750 – 1,250K in M giants ...

We describe an integrated, molecular-absorbance, atomic absorption instrument for studying metal/ligand binding in clinical samples. For an interface between the "high-performance" liquid chromatograph and the atomic absorption instrument we used a flow-injection sample manipulator, thus allowing both the chromatograph and the atomic absorption detector to operate at their separate optimum cond...

A new spectroscopic technique that is based on molecular dispersion spectroscopy and enables new capabilities in chemical detection as compared to well-established laser absorption spectroscopy will be discussed in this paper. Differential optical dispersion spectroscopy (DODiS) enables simultaneous measurement and comparison of two gas samples. This is performed through simultaneous detection ...

Vibrational overtone spectroscopy of molecules is a powerful tool for drawing information on molecular structure and dynamics. It relies on absorption of near infrared radiation (NIR) by molecular vibrations. Here we show the experimental evidence of giant enhancement of the absorption of light in solutions of organic molecules due to the switch from ballistic to diffusive propagation of light ...

Recent progress of the XANES (X-ray absorption near-edge structure) spectral analysis methods for the structure characterization of metal complexes (MC) in solution is reviewed. Typical examples showing the scheme of the apparatus for XAFS (X-ray absorption fine structure) data collection, preparation and handling of solution samples, data treatment and analysis for XANES spectra, and future of...
