An understanding of the transport solar wind plasma into and throughout terrestrial magnetosphere is crucial to space science weather. For non-active periods, there little agreement on where how entry might occur. Moreover, behaviour in high-latitude region behind magnetospheric cusps, for example, lobes, poorly understood, partly because lack coverage by previous missions. Here, using Cluster multi-spacecraft data, we report an unexpected discovery regions Earth's tailward cusps. From...
Using HST observations of 147 host galaxies low-mass black holes (BHs), we systematically study the structures and scaling relations these active galaxies. Our sample is selected to have central BHs with virial masses ~10^5-10^6 solar mass. The total I-band magnitudes -23.2<M_I<-18.8 mag bulge -22.9<M_I<-16.1 mag. Detailed bulge-disk-bar decompositions GALFIT show that 93% extended disks, 39% bars 5% no bulges at all limits our observations. Based on Sersic index bulge-to-total ratio,...
Abstract. Magnetic holes with relatively small scale sizes, detected by Cluster and TC-1 in the magnetotail plasma sheet, are studied this paper. It is found that these magnetic spatial structures they not depressions generated flapping movement of current sheet. Most (93%) were observed during intervals Bz larger than Bx, i.e. more likely to occur a dipolarized field topology. Our results also suggest occurrence might have close relationship dipolarization process. The typically size...
Current densities associated with dipolarization fronts (DFs) have been calculated in the geomagnetic tail using curlometer technique applied to high‐resolution magnetic field data obtained by four Cluster spacecraft. We then use relation characterize behavior of field‐aligned current (FAC) during 25 DF events. Our results show that magnitude FAC density ( J // ) ranges from 5 20 nA/m 2 , and they are observed Northern Southern Hemispheres flowing along both directions ‐field. The FACs...
We study the spatially resolved star formation history and molecular gas distribution of 58 nearby galaxies, using integral field spectroscopy from CALIFA survey CO $J=1\rightarrow 0$ intensity mapping CARMA EDGE survey. use 4000 \AA\ break (D$_n$4000), equivalent width H$\delta$ absorption line (EW H$\delta_A$), H$\alpha$ emission H$\alpha$) to measure recent (SFH) these galaxies. radial profiles three SFH indicators mass surface density, which we level centrally enhanced concentration....
We investigate the recent star formation history (SFH) in inner region of 57 nearly face-on spiral galaxies selected from Calar Alto Legacy Integral Field Area (CALIFA) survey. For each galaxy we use integral field spectroscopy CALIFA to obtain two-dimensional maps and radial profiles three parameters that are sensitive indicators SFH: 4000\AA\ break (D$_n$(4000)), equivalent width H$\delta$ absorption (EW(H$\delta_A$)) H$\alpha$ emission (EW(H$\alpha$)). have also performed photometric...
In this study, a self-cooling laboratory system was used for pressure−shift freezing (PSF), and the effects of (PSF) at 150 MPa on quality largemouth bass (Micropterus salmoides) during frozen storage −30 °C were evaluated compared with those conventional air (CAF) liquid immersion (LIF). The thawing loss cooking PSF significantly lower than CAF LIF whole period. loss, L* value, b* value TBARS fish increased storage. After 28 days storage, values 0.54 0.65, respectively, higher (p < 0.05)...
Abstract Using data from ALFALFA, xGASS, H i -MaNGA, and the Sloan Digital Sky Survey (SDSS), we identify a sample of 47 “red but -rich” (RR) galaxies with near-UV (NUV) − r > 5 unusually high -to-stellar mass ratios. We compare optical properties local environments between RR control -normal” (RN) that are matched in stellar color. The two samples similar typical massive red (quenched) Universe. tends to be associated slightly lower-density has lower clustering amplitudes smaller...
Abstract The sudden enhancements of magnetic strength, named peaks (MPs), are often observed in the magnetosheath magnetized planets. They usually identified as flux ropes (FRs) or mirror mode structures. Previous studies MPs mostly on magnetohydrodynamics (MHD) scale. In this study, an electron scale MP is reported Earth magnetosheath. We present a typical case with ~7 gyroradii and duration ~0.18 s. A strong disturbance associated electrical current detected. Electron vortex found...
Ensuring food safety and quality is paramount for consumers. Water, a fundamental component of food, exhibits diverse crystalline structures under high pressure (HP) experiences alterations in freezing points. Exploiting these water characteristics has spurred the development innovative high-pressure sub-zero temperature (HPST) techniques. This review systematically categorizes HPST technologies based on their adherence to temperature-pressure phase diagram, encompassing (HPF), thawing...
We present empirical relations between the global dust reddening and other physical galaxy properties including Hα luminosity, surface brightness, metallicity axial ratio for star-forming disc galaxies. The study is based on a large sample of ∼22 000 well-defined galaxies selected from Sloan Digital Sky Survey. parametrized by colour excess E(B−V) derived Balmer decrement. Besides dependency luminosity/surface brightness gas phase metallicity, it also correlated with inclination, in sense...

The observed rotated in direction opposite to that associated with positive pulses. was moving tailward, as confirmed global magnetohydrodynamics (MHD) simulation. In addition, the equivalent ionospheric currents (EICs) deduced ground magnetometer station reveal current...
