CONNECTION AMONG ENVIRONMENT, CLOUD-CLOUD COLLISION SPEED, AND STAR FORMATION ACTIVITY IN THE STRONGLY BARRED GALAXY NGC 1300

Redazione
(AGENPARL) – GARCHING (GERMANY), gio 25 febbraio 2021 First Author: Maeda, FumiyaInstruments: ALMA_Band_3, ALMA_Band_6, ALMA_BandsProgramIDs: 2015.1.00925.S, 2017.1.00248.S, 2018.1.01651.SBibCode: 2021MNRAS.502.2238M Cloud-cloud collision (CCC) has been suggested as a mechanism to induce massive star formation. Recent simulations suggest that a CCC speed is different among galactic-scale environments, which is responsible for observed......

AB INITIO RATE COEFFICIENTS FOR REACTIONS OF 2,5-DIMETHYLHEXYL ISOMERS WITH O2: TEMPERATURE -AND PRESSURE-DEPENDENT BRANCHING RATIOS

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), mar 16 febbraio 2021 Chemical kinetics of O2-addition to alkyl radicals (R), termed first O2-addition in the oxidation mechanism of alkanes, are of central importance to next-generation combustion strategies designed for operation in the low- to intermediate-temperature region (< 1000 K). In the present work,......

CENTRALLY CONCENTRATED MOLECULAR GAS DRIVING GALACTIC-SCALE IONIZED GAS OUTFLOWS IN STAR-FORMING GALAXIES

Redazione
(AGENPARL) – GARCHING (GERMANY), dom 14 febbraio 2021 First Author: Hogarth, L. M.Instruments: ALMA_Band_3, ALMA_BandsProgramIDs: 2017.1.00601.SBibCode: 2021MNRAS.500.3802H We perform a joint analysis of high spatial resolution molecular gas and star-formation rate (SFR) maps in main-sequence star-forming galaxies experiencing galactic-scale outflows of ionized gas. Our aim is to understand the mechanism......

BORN TO BE DIFFERENT: THE FORMATION PROCESS OF CU-NANOPARTICLES TUNES THE SIZE-TREND OF THE ACTIVITY FOR CO$_2$ TO CH$_4$ CONVERSION

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), ven 12 febbraio 2021 We investigate the impact of the formation process on the distribution of adsorption sites of Cu nanoparticles and hence on their activity. Using molecular dynamics, we model formation pathways characteristic of physical synthesis routes as the annealing of a liquid droplet,......

ASTRONOMERS IDENTIFY NEW METHOD OF PLANET FORMATION

Redazione
(AGENPARL) – CAMBRIDGE (ENGLAND), ven 12 febbraio 2021 In the last 25 years, scientists have discovered over 4000 planets outside our solar system. From relatively small rock and water worlds to blisteringly hot gas giants, these planets display a remarkable variety. This variety is not unexpected. The computer models which......

THE ROLE OF INTERMOLECULAR FORCES IN IONIC REACTIONS: THE SOLVENT EFFECT, ION-PAIRING, AGGREGATES AND STRUCTURED ENVIRONMENT

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), lun 08 febbraio 2021 The environment enclosing an ionic species has a critical effect on its reactivity. In a more general sense, medium effects are not limited to the solvent, but involve the counter ion effect (ion pairing), formation of larger aggregates and structured environment......
