Abstract Occupying the intermediate-mass regime of accretion-jet parameter space, radio continuum emission from active galactic nuclei (AGNs) with black hole mass M BH ≲ 10 6 ⊙ (low-mass AGNs) is a valuable probe to physics relativistic jets. Yet number low-mass AGNs detection rather limited so far (≈40 in total). In this work, we make two efforts search for counterparts largest sample optically selected AGNs. First, collect recent data releases Square Kilometre Array (SKA) pathfinders such...
Introduction Accurate and rapid carbon accounting method for the power industry is crucial to support China’s low-carbon transformation. Currently, emission methods are based on slowly updated fuel statistics or expensive monitoring equipment, resulting in high costs delays estimation. Power data offers real-time availability, accuracy, resolution, exhibits a strong correlation with emissions. These characteristics provide pathway achieving precise annual accountings. However, inherently...
Abstract We report the discovery of a binary millisecond pulsar (namely PSR J1641+3627F or M13F) in globular cluster (GC) M13 (NGC 6205) and timing solutions M13A to F using observations made with Five-hundred-meter Aperture Spherical radio Telescope. has spin period 3.00 ms an orbital 1.4 days. The most likely companion mass is 0.13 M ⊙ . E all have short periods small derivatives. also confirm that J1641+3627E (also M13E) black widow around 0.02 find systems low eccentricities compared...
Abstract We developed a pulsar search pipeline based on PulsaR Exploration and Search TOolkit (PRESTO). This simply runs dedispersion, Fast Fourier Transform (FFT) acceleration in process-level parallel to shorten the processing time.With two strategies, can highly time both normal searches searches. was first tested with Parkes Multibeam Pulsar Survery (PMPS) data discovered new faint pulsars. Then, it successfully applied Five-hundred-meterAperture Spherical radio Telescope (FAST) drift...
The recent advancements in exoplanet observations enable the potential detection of exo-Venuses, rocky planets with carbon-rich atmospheres. How extended these atmospheres can be, given high carbon abundances, has not been studied. To answer this, we present a model for theoretical class exoplanets - puffy Venuses characterized by thick, carbon-dominated equilibrium global magma oceans. Our accounts and hydrogen partition between atmosphere ocean, as well C-H-O chemistry throughout...
It is conjectured that coherent re-emission of cyclotron resonance absorption could result in pulsar giant pulses. This conjecture seems reasonable as it can naturally explain the distribution pulsars with pulses on $P$-$\dot{P}$ diagram.
With the largest dish Five-hundred-meter Aperture Spherical radio Telescope (FAST), both mean and single pulses of PSR B2016$+$28, especially including single-pulse structure, are investigated in detail this study. The pulse profiles at different frequencies can be well fitted a conal model, peak separation intensity-dependent increases with intensity. integrated obviously frequency dependent (pulse width decreases by $\sim\,20\%$ as from 300 MHz to 750 MHz), but structure changes slightly...
Abstract The Zone of Avoidance (ZoA) is a region low galactic latitude that heavily obscured by the Milky Way. Observations with radio telescopes are basically unaffected dust extinction and can unveil structure behind it through One scientific goals Five-hundred-meter Aperture Spherical Telescope (FAST) to search for neutral hydrogen understand large-scale physics explore origin evolution universe. We take 15,500 IRAS (the Infrared Astronomical Satellite) galaxies from PSC z (“Point Source...
We present a method by using the phase characteristics of radio observation data for pulsar search and candidate identification. The are relations between signal correction in frequency-domain, we regard it as new diagnostic characteristic. Based on characteristics, is presented: calculating DM (dispersion measure) -- frequency to select frequencies, then confirming candidates broadband signals. this method, performed test short M15 M71, which were observed Five-hundred-meter Aperture...
