빠른 전파 폭발 호스트 은하 및 이벤트 발생률 밀도에 대한 재조사
빠른 전파 폭발(FRB)의 기원을 이해하기 위해서는 호스트 은하의 분산 측정(DM) 기여도를 고려한 이벤트 발생률 밀도 연구가 중요하며, 본 연구에서는 CHIME/FRB 데이터를 분석하여 리피터 및 비리피터 FRB의 체적 발생률을 추정하고, 이를 기존 이론 및 다른 천체 현상과 비교 분석하여 FRB 기원 모델을 제한하고자 한다.
The Impact of Host Galaxy Dispersion Measure on Fast Radio Burst Event Rates and Origin Theories
Accurately accounting for the dispersion measure contribution from host galaxies is crucial for estimating the volumetric rates of fast radio bursts (FRBs) and understanding their origins, as it significantly impacts distance calculations and event rate estimations.
Detection of a Gamma-Ray Flare Potentially Associated with Fast Radio Burst Source FRB 20240114A
This research paper reports the first-ever detection of a gamma-ray flare coincident with a hyperactive fast radio burst source, FRB 20240114A, challenging existing theories about FRB engines and suggesting a powerful, long-lived energy source.
Systematic Search for Persistent Radio Sources Associated with Repeating Fast Radio Bursts Detected by CHIME/FRB
While two repeating fast radio bursts (FRBs) have confirmed persistent radio source (PRS) counterparts, a systematic search for PRSs toward 37 CHIME/FRB repeaters using archival and new VLA data revealed only two promising candidates (20181030A-S1 and 20190417A-S1), suggesting that bright PRSs are not ubiquitous among repeating FRBs.
A Morphological Study of 32 Repeating Fast Radio Bursts at Microsecond Time Scales Using CHIME/FRB Data
Repeating fast radio bursts (FRBs) exhibit distinct morphological characteristics compared to non-repeating FRBs, suggesting potential differences in their emission mechanisms or progenitor environments, but further research is needed to understand the observed variations and their implications.
The Source of Fast Radio Bursts: New Evidence Points to Unconventionally Created Magnetars in Massive Galaxies
New research suggests that fast radio bursts (FRBs), brief but powerful flashes of radio waves from distant galaxies, may originate from magnetars, a rare type of neutron star, formed in unconventional ways within massive galaxies.
Fast Radio Bursts Show a Preference for Massive Star-Forming Galaxies as Hosts
Fast radio bursts (FRBs) are more likely to originate in massive, metal-rich galaxies, suggesting that their sources, likely magnetars, are preferentially formed from the core-collapse supernovae of merged stellar remnants in these environments.
FRB集団における観測された傾向とピーク輝度密度分布における双峰性
高速電波バースト (FRB) 集団の分析により、輝度密度に基づいて2つの異なるカテゴリに分類できることが明らかになり、これはマグネターのグリッチによって説明できる可能性があります。
The Use of Fast Radio Bursts as Probes of Cosmology
Fast radio bursts (FRBs) are a powerful new tool for probing the distribution of baryonic matter in the universe and addressing fundamental cosmological questions.
Discovery and Host Galaxy Association of FRB 20240209A: A Repeating Fast Radio Burst in the Outskirts of a Quiescent Galaxy
FRB 20240209A, a newly discovered repeating fast radio burst, has been localized to the outskirts of a quiescent galaxy, challenging current understanding of FRB progenitor formation channels and suggesting a delayed formation scenario.
