A gas-phase “top-down” chemical link between aldehydes and alcohols
Frontiers in Astronomy and Space SciencesIntroductionAlcohols and aldehydes represent two key classes of interstellar complex organic molecules (COMs). This work seeks to better understand their possible chemical connections, with a focus on such molecules in the sources of the star-forming ...

FAST Search for Circumstellar Atomic Hydrogen. IV. Bubbles Associated with Planetary Nebulae
The Astronomical JournalInvestigating the bubbles generated by the interaction between asymptotic giant branch stellar outflows and the interstellar medium (ISM) is pivotal for elucidating the mechanism by which evolved low- to intermediate-mass stars enrich the ISM with heavy ...

Simulating supernova feedback in galaxy disks [PDF]
, 2012 In this thesis I examine supernova feedback in hydrodynamical simulations of galaxy disks. Understanding this process entails the numerical evaluation of cooling in radiative shocks, and we present a set of simulations using two widely used numerical ...

Light storage and control of photon-photon interactions in a cold Rydberg gas [PDF]
, 2013 The effect of strong interatomic interactions on an optical field stored in Rydberg states of a cold atomic gas is investigated. Due to their large dipole moments Rydberg atoms interact very strongly with each other.

Investigation into Triggered Star Formation by Radiative Driven Implosion [PDF]
, 2016 When massive stars form, they emit strong, hydrogen ionising radiation fields into their molecular cloud environment, forming HII regions. This is believed to be capable of inducing effects which can trigger further star formation through a process known

Spatial distribution of interstellar gas in the innermost 3 kpc of our galaxy
, 2007 International audienceWe review the present observational knowledge on the spatial distribution and the physical state of the different (molecular, atomic and ionized) components of the interstellar gas in the innermost 3 kpc of our Galaxy - a region ...

H i Content of Group Galaxies from the FAST All Sky H i Survey
The Astrophysical JournalWe investigate the atomic gas (H i ) content of galaxies in groups using early data from the Five-hundred-meter Aperture Spherical Radio Telescope (FAST) All Sky H i survey. Taking advantage of FAST’s blind, wide-area coverage and uniform sensitivity, we

Interstellar gas, dust and diffuse bands in the SMC
, 2007 Aims. In order to gain new insight into the unidentified identity of the diffuse interstellar band (DIB) carriers, this paper describes research into possible links between the shape of the interstellar extinction curve ( including the 2175 angstrom bump

Structural and gas-sensing properties of CuO–CuxFe3−xO4 nanostructured thin films [PDF]
, 2010 Nanocrystalline CuO–CuxFe3−xO4 thin films were developed using a radio-frequency sputtering method followed by a thermal oxidation process. Thin films were deposited applying two very different conditions by varying the argon pressure and the target-to ...
