Hierarchiral 4-tetranitro copper(II)phthalocyanine based metal organic framework hybrid composite with improved electrocatalytic efficiency towards hydrogen evolution reaction
(Elsivier, 2019)
A novel hybrid-hybrid nanocomposite based on 4-tetranitro copper(II)phthalocyanine (TNCuPc) grown on metal
organic frameworks (MOF) as a noble metal-free catalyst for hydrogen evolution reaction (HER) was developed
by a ...
Preface Metamorphism and Orogenic belts—response from micro- to macro-scale
(Springerlink, 2019)
The geological toolbox for the analysis of orogenic processes has seen substantial additions over the recent decades. Major advances have been made in the ability to simulate geological conditions and processes by computer ...
Surveys with small optical telescopes
(Oxford academic, 2019)
odern astrophysics owes its existence to small-telescope surveys dating back to the 18th century, for example
Flamsteed (1725). In the 19th century, Argelander’s survey based on visual observations with small telescopes
and ...
Multi-instrument observations of large-scale atmospheric gravity waves/traveling ionospheric disturbances associated with enhanced auroral activity over Svalbard
(Elsevier, 2019-09-03)
This study reports on observations of large-scale atmospheric gravity waves/traveling ionospheric disturbances (AGWs/TIDs) using Global Positioning System (GPS) total electron content (TEC) and Fabry–Perot Interferometer’s ...
Semi-analytic forecasts for jwst – ii. Physical properties and scaling relations for galaxies at z = 4–10
(Oxford academic, 2019)
The long anticipated James Webb Space Telescope (JWST) will be able to directly detect large
samples of galaxies at very high redshift. Using the well-established, computationally efficient
Santa Cruz semi-analytic model, ...
Imprints of temperature fluctuations on the z ∼ 5 Lyman-α forest: a view from radiation-hydrodynamic simulations of reionization
(Oxford academic, 2019)
Reionization leads to large spatial fluctuations in the intergalactic temperature that can persist
well after its completion. We study the imprints of such fluctuations on the z ∼ 5 Ly α
forest flux power spectrum using ...
IQ-Collaboratory 1.1: The Star-forming Sequence of Simulated Central Galaxies
(The astrophysical journal, 2019)
A tightly correlated star formation rate (SFR)–stellar mass relation of star-forming galaxies, or star-forming sequence (SFS), is a key feature in galaxy property-space that is predicted by modern galaxy formation models. ...
Asteroseismology of Massive Stars with the TESS Mission: The Runaway β Cep Pulsator PHL 346 = HN Aqr
(The Astrophysical journal letter, 2019)
We report an analysis of the first known β Cep pulsator observed by the Transiting Exoplanet Survey Satellite (TESS) mission, the runaway star PHL 346 = HN Aqr. The star, previously known as a singly periodic pulsator, has ...
Cosmological constraints on post-Newtonian parameters in effectively massless scalar-tensor theories of gravity
(2019)
We study the cosmological constraints on the variation of Newton’s constant and on post-Newtonian
parameters for simple models of the scalar-tensor theory of gravity beyond the extended Jordan-BransDicke theory. We restrict ...
Energy-momentum tensor and helicity for gauge fields coupled to a pseudoscalar inflaton
(University of the Western Cape, 2019)
We study the energy-momentum tensor and helicity of gauge fields coupled through $g \phi F \tilde{F}/4$ to a pseudo-scalar field $\phi$ driving inflation. Under the assumption of a constant time derivative of the background ...
