In this catalog we present the updated set of spectral analyses GRBs detected by Fermi Gamma-Ray Burst Monitor (GBM) during its first four years operation. It contains two types spectra, time-integrated fits and at brightest time bin, from 943 triggered GRBs. Four different models were fitted to data, resulting in a compendium more than 7500 spectra. The analysis was performed similarly, but not identically Goldstein et al. 2012. All 487 have been re-fitted using same methodology as that 456...
The Fermi Gamma-ray Burst Monitor (GBM) is designed to enhance the scientific return from in studying gamma-ray bursts (GRBs). In its first two years of operation GBM triggered on 491 GRBs. We summarize criteria used for triggering and quantify general characteristics GRBs, including their locations, durations, peak flux, fluence. This catalog an official product science team, data files containing complete results are available High-Energy Astrophysics Science Archive Research Center.
Covalent organic frameworks (COFs) have received considerable interest because of their advanced applications. However, low dispersibility and aqueous stability are intractable issues limiting biomedical application. To address the issue, water-dispersible nanocomposites (COF@IR783) produced through assembly cyanines COFs proposed prepared. Therefore, a strategy "killing three birds with one stone" is developed. First, exhibit superior compared to COFs. The nanosized morphology negative...
Immune checkpoint blockade therapy (ICT) has shown potential in the treatment of multiple tumors, but suffers poor response rate clinic. We found that even combining ICT with chemotherapy, which was wildly used clinical trials, failed to achieve satisfactory tumor inhibition B16F10 model. Thus, we further constructed a previously unexplored immune cocktail and realized boosting cancer-immunity cycle. Cocktail consisted two kinds microenvironment-responsive drug gene delivery nanoparticles...
We report on NICER observations of the Magnetar SGR~1935+2154, covering its 2020 burst storm and long-term persistent emission evolution up to $\sim90$ days post outburst. During first 1120~seconds taken April 28 00:40:58 UTC we detect over 217 bursts, corresponding a rate $>0.2$ bursts s$^{-1}$. Three hours later is at 0.008 s$^{-1}$, remaining comparatively low level thereafter. The $T_{90}$ duration distribution peaks 840~ms; waiting times next fit with log-normal an average 2.1 s. 1-10...
Tumor nanovaccines have potential applications in the prevention and treatment of malignant tumors. However, it remains a longstanding challenge exploiting efficient nanocarriers for inducing potent specifically cellular immune responses. Toward this objective, we herein explore an intensive tumor immunotherapeutic strategy by combining mannosylated gene regulated PD-L1 blockade stimulation killing activity. Here, fabricate mannose modified PLL-RT (Man-PLL-RT) mediated with dendritic cells...
The megajansky radio burst, FRB 20200428, and other bright bursts detected from the Galactic source SGR J1935+2154 suggest that magnetars can make fast (FRBs), but emission site mechanism of FRB-like are still unidentified. Here, we report emergence a pulsar phase magnetar 5 months after 20200428. Pulses were in 16.5 hours over 13 days using Five-hundred-meter Aperture Spherical Telescope, with luminosities about eight decades fainter than pulses emitted narrow window anti-aligned x-ray...
GRB 221009A is the brightest gamma-ray burst ever detected since discovery of this kind energetic explosions. However, an accurate measurement prompt emission properties very challenging due to its exceptional brightness. With joint observations \textit{Insight}-HXMT and GECAM-C, we made unprecedentedly during first $\sim$1800 s 221009A, including precursor, main (ME, which dominates in flux), flaring early afterglow, hard X-ray soft band from $\sim$ 10 keV 6 MeV. Based on GECAM-C...
Abstract The milestone discovery of GW170817-GRB 170817A-AT 2017gfo has shown that gravitational waves (GWs) could be produced during the merger a neutron star–neutron star/black hole and in electromagnetic (EM) waves, gamma-ray burst (GRB) kilonova (KN) are generated sequence after merger. Observationally, however, EM properties before phase still unclear. Here we report peculiar precursor KN-associated long-duration GRB 211211A, providing evidence This lasts ∼0.2 s, waiting time between...
We present extensive optical observations of a Type IIn supernova (SN) 2010jl for the first 1.5 years after discovery. The UBVRI light curves demonstrated an interesting two-stage evolution during nebular phase, which almost flatten out about 90 days from maximum. SN has one highest intrinsic H_alpha luminosity ever recorded IIn, especially at late suggesting strong interaction ejecta with dense circumstellar material (CSM) ejected by progenitor. This is also indicated remarkably Balmer...
Abstract We analyzed broadband X-ray and radio data of the magnetar SGR J1935+2154 taken in aftermath its 2014, 2015, 2016 outbursts. The source soft spectrum <10 keV is well described with a blackbody+power-law (BB+PL) or 2BB model during all three Nuclear Spectroscopic Telescope Array observations revealed hard tail, PL photon index Γ = 0.9, extending up to 50 keV, flux comparable one detected keV. Imaging analysis Chandra did not reveal small-scale extended emission around source....
Abstract We present timing and time-integrated spectral analysis of 127 bursts from SGR J1935+2154. These were observed with the Gamma-ray Burst Monitor on Fermi Space Telescope Alert Neil Gehrels Swift Observatory during source’s four active episodes 2014 to 2016. This activation frequency makes J1935+2154 most burst prolific transient magnetar. find average duration all detected be much shorter than typical, anticipated value. fit spectra two blackbody functions, a Comptonized model three...
Abstract Fast radio bursts (FRBs) are short pulses observed in band from cosmological distances, some of which emit repeating bursts. The physical origins these mysterious events have been subject to wide speculations and heated debates. One class models invoke soft gamma-ray repeaters (SGRs), or magnetars, as the sources FRBs. Magnetars rotating neutron stars with extremely strong magnetic field can sporadically X-ray (keV) (sub-MeV) duration 102 s 102 s. However, even though bright no...
Abstract We present temporal and time-integrated spectral analyses of 148 bursts from the latest activation SGR J1935+2154, observed with Fermi/Gamma-ray Burst Monitor 2019 October 4 through 2020 May 20, excluding an ∼130 s segment a very high burst density on April 27. The presented here are slightly longer softer than earlier activations as well other magnetars. long-term evolution trend is interpreted being associated increase in average plasma loading magnetosphere during bursts. also...
The origin(s) and mechanism(s) of fast radio bursts (FRBs), which are short pulses from cosmological distances, have remained a major puzzle since their discovery. We report strong Quasi-Periodic Oscillation(QPO) 40 Hz in the X-ray burst magnetar SGR J1935+2154 associated with FRB 200428, significantly detected Hard Modulation Telescope (Insight-HXMT) also hinted by Konus-Wind data. QPOs only been rarely detected; our 3.4 sigma (p-value is 2.9e-4) detection QPO reported here reveals...
