Physical Properties of Massive Compact Starburst Galaxies with Extreme Outflows
(2021-12-29)
We present results on the nature of extreme ejective feedback episodes and the physical conditions of a population of massive (M * ∼ 1011 M ⊙), compact starburst galaxies at z = 0.4–0.7. We use data from Keck/NIRSPEC, SDSS, ...
Optimal Fractional-Order PI Control Design for a Variable Speed PMSG-Based Wind Turbine
(2021-12-29)
This paper focusses on the design of optimal control strategies for a variable-speed wind energy system based on Permanent Magnet Synchronous Generator (PMSG). The fractional order PI controller, denoted PIλ, is an extension ...
Finding Rare Quasars: VLA Snapshot Continuum Survey of FRI Quasar Candidates Selected from the LOFAR Two-Metre Sky Survey (LoTSS)
(2021-12-22)
The radiative and jet power in active galactic nuclei is generated by accretion of material on to supermassive galactic-centre black holes. For quasars, where the radiative power is by definition very high, objects with ...
Optimization of the Observing Cadence for the Rubin Observatory Legacy Survey of Space and Time: A Pioneering Process of Community-focused Experimental Design
(2021-12-22)
Vera C. Rubin Observatory is a ground-based astronomical facility under construction, a joint project of the National Science Foundation and the U.S. Department of Energy, designed to conduct a multipurpose 10 yr optical ...
GTC/CanariCam Deep Mid-infrared Imaging Survey of Northern Stars within 5 pc
(2021-12-15)
In this work we present the results of a direct imaging survey for brown dwarf companions around the nearest stars at the mid-infrared 10 micron range (λ c = 8.7 μm, Δλ = 1.1 μm) using the CanariCam instrument on the 10.4 ...
Future Trends and Aging Analysis of Battery Energy Storage Systems for Electric Vehicles
(2021-12-14)
The increase of electric vehicles (EVs), environmental concerns, energy preservation, battery selection, and characteristics have demonstrated the headway of EV development. It is known that the battery units require special ...
A virtual force interaction scheme for multi-robot environment monitoring
(2021-12-09)
The autonomous multi-robot system is an emerging technology that has a wide range of potential applications, such as environmental monitoring, exploration of unknown area, battlefield surveillance, and search and rescue. ...
The Radioactive Nuclei 26Al and 60Fe in the Cosmos and in the Solar System
(2021-12-09)
The cosmic evolution of the chemical elements from the Big Bang to the present time is driven by nuclear fusion reactions inside stars and stellar explosions. A cycle of matter recurrently re-processes metal-enriched stellar ...
The first retrieval of a substellar subdwarf: A cloud-free SDSS J125637.13-022452.4
(2021-12-08)
We present the first retrieval analysis of a substellar subdwarf, SDSS J125637.13-022452.4 (SDSS J1256-0224), using the Brewster retrieval code base. We find SDSS J1256-0224 is best fit by a cloud-free model with an ion ...
