Skipping a beat: discovery of persistent quasi-periodic oscillations associated with pulsed fraction drop of the spin signal in M51 ULX-7 [PDF]

Astronomy & Astrophysics
The discovery of pulsations in (at least) six ultraluminous X-ray sources (ULXs) has shown that neutron stars can accrete at (highly) super-Eddington rates, challenging the standard accretion theories. with a spin signal of $P is the pulsating ULX (PULX)

The radio jet in M51

The Astronomical Journal, 1992
High-sensitivity VLA observations of M51 at 6 cm wavelength with sub-arcsecond resolution have resolved the southern extra-nuclear cloud identified by Ford et al. [ApJ, 293, 132 (1985)]. These observations reveal a short (3-4"), sinuous jetlike feature connecting the weak nuclear radio source to a bright arcuate ridge of radio emission that dominates ...

Clues to the formation of spiral structure in M51 from the ages and locations of star clusters [PDF]

, 2017
We determine the spatial distributions of star clusters at different ages in the grand-design spiral galaxy M51 using a new catalog based on multi-band images taken with the Hubble Space Telescope (HST). These distributions, when compared with the spiral

The molecular gas distribution in M51

The Astrophysical Journal, 1983
CO emission has been mapped along four strips in M51 using the 14 m Five College Radio Astronomy Observatory telescope (HPBW = 50'') in order to sample the radial distribution of molecular gas. The derived abundance of H/sub 2/ shows that three-fourths of the interstellar medium (ISM) nucleons are in H/sub 2/ rather than H I in the disk at ...

Biosynthesis of Silver Nanoparticles Using Black Pepper (Piper nigrum) Seed Extract and Evaluation of Their Cytotoxicity [PDF]

Chem Biodivers
This study reports the green biosynthesis of piperine‐functionalized silver nanoparticles from Piper nigrum seed extract, followed by comprehensive physicochemical characterization and in vitro cytotoxic evaluation. The results confirm successful nanocomposite formation and demonstrate a marked enhancement of cytotoxic activity against gastric cancer ...

Hydrogen Radio Recombination Line Emission from M51 and NGC628 [PDF]

, 2018
We report the discovery of hydrogen radio recombination line (RRL) emission from two galaxies with star formation rates (SFRs) similar to that of the Milky Way: M51 and NGC628.

Determining the Factors of the Employees’ Intention to Stay or Leave in the Slovak’s SMEs

International Journal of Entrepreneurial Knowledge, 2019
A large number of Slovak small and medium enterprises (SMEs) are confronted with often-leaving employees. This situation can have a devastating effect; thus, the ability to predict and early detect the employees’ intention to stay or leave to another ...

Giant Molecular Associations in M51 [PDF]

Proceedings of the International Astronomical Union, 2006
AbstractWe present a 12CO 2-1 map of M51 (Schuster et al. 2006) at 11″ resolution observed with HERA at the IRAM-30m telescope. The map covers the companion galaxy NGC5195 as well as the south-western arm out to 12 kpc. Using the IRAM-30m data and the clump finding procedure GAUSSCLUMPS (Stutzki et al.

Upcycling orange by‐product: phenolic bioaccessibility and technological features of jelly candies enriched with hydroalcoholic and enzymatic extracts

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Phenolic extracts are recognized for their health‐promoting properties, although some physicochemical characteristics limit their food applications. The present study aimed to valorize orange juice by‐products through enzymatic and hydroalcoholic extraction to obtain flavonoid ingredients and to evaluate their application in pectin ...
