Chinese telescope FAST discovered 76 new faint pulsars

Published

These pulsars are special in the sense that they periodically emit a pulse as they spin, which is why they are known as periodic radio frequency emission sources (RRATs).

Pulsars, or rapidly rotating neutron stars, are formed from the remains of the cores of massive stars after supernova explosions. Their high density and rapid rotation make them an ideal laboratory for studying the laws of physics under extreme conditions.

Unlike most pulsars, which emit pulses continuously, RRAT is difficult to find in normal pulsar search mode. They are isolated pulse by pulse from a huge amount of data obtained using a highly sensitive radio telescope.

Since the discovery of the first RRAT in 2006, radio telescopes around the world have discovered more than 160 RRATs. Detailed studies of several faint pulsars indicate that they are pulsars with special physical properties in the magnetosphere, and constitute about 5% of the total number of pulsars.

The Beijing Astronomical Observatory (NAOC) research team developed a new system for searching for individual pulses and systematically searched for individual pulses in data obtained from the 2020 FAST Galactic Pulsar Snapshot Survey.

The 76 RRATs discovered by the new method account for about 12% of the total number of pulsars discovered in the FAST study, according to Han Jinglin, a leading researcher in the field. This suggests that there are more such periodically emitting pulsars than previously thought.

To better understand the physical properties of RRATs, scientists also used FAST to observe 59 known RRATs detected by international telescopes. The polarization signals of these periodically emitted pulses detected by FAST indicate that they are emitted from the same region of the neutron star’s magnetosphere as normal pulses, according to the study.

“The study has important implications for understanding the dense remnants of dead stars in the Milky Way and their emission characteristics,” Han said, adding that highly sensitive radio telescopes such as FAST are the best tools for detecting such amazing pulsars.

The car features a new set of 18-inch aluminum wheels with a more sophisticated design and bronze finish. These wheels are paired with Yokohama Geolandar off-road tires. The Jaos roof rack and luggage compartment enhance the Land Cruiser’s cargo-carrying capabilities. A rubber trunk mat is included to help keep the interior clean during outdoor activities that may include hauling dirty equipment. Modelista adds a touch of retro flair to the Land Cruiser’s interior with woodgrain accents. Additionally, the tuner offers standard LED interior lighting, tinted glass, license plate bolts and more.

Chevrolet Suburban 2025 and Tahoe 2025 presented

Chevrolet has unveiled the 2025 Chevrolet Suburban and 2025 Tahoe. The most obvious changes are visible at the front, where a Silverado EV-style fascia has been added. The larger daytime running lights are housed in gloss black housings. Standard on all models is a high-gloss black grille, and some trims have unique textures up front—like the Z71’s black mesh and High Country Galvano chrome trim.

The sporty RST and the flagship High Country now offer massive 24-inch wheels as an option. Overall, the new Tahoe and Suburban look the same as before. But there are more changes inside. Every trim comes standard with a new 17.7-inch touchscreen and 11.0-inch digital instrument cluster. A redesigned instrument panel improves visibility. The gear selector (previously a set of buttons on the center console) is again located on the steering column. The console has also been slightly redesigned, and a power armrest with hidden storage underneath returns to the range as a gimmicky option.

Wireless Apple CarPlay and Android Auto remain, and the electronics package also includes some new features. Towing is reportedly made easier with a new app that takes into account the length and width of the trailer to estimate the path when turning and driving forward, monitoring the health of your trailer’s tires, and a boat launching guide that provides step-by-step instructions. The cloud-connected camera system provides owners with a live video feed via a smartphone app.

The 2025 Suburban and Tahoe come standard with automatic emergency braking, lane-centering technology, blind-spot monitoring, front and side pedestrian detection and adaptive cruise control. Additionally, the advanced Super Cruise driver assistance package will be available on LT, RST, Premier and High Country trims – previously only offered on the latter two trims.

A sophisticated rear-seat monitoring system sensitive enough to detect heartbeat and breathing patterns is standard. There is also an internal chamber.

Chevrolet’s proven 3.0-liter Duramax turbodiesel will now be offered in Z71 trim in 2025, with the automaker saying many of its customers wanted the efficiency and smoothness of the inline-six engine, as well as the capabilities of the off-road package. What’s more, the Suburban and Tahoe now get a high-performance diesel version that produces 305 hp. The 5.3-liter and 6.2-liter V8 petrol engines remain unchanged.
