The biorhythm theory is the pseudoscientific idea that peoples' daily lives are significantly affected by rhythmic cycles with periods of exactly 23, 28 and 33 days, [2] [3] [4] typically a 23-day physical cycle, a 28-day emotional cycle, and a 33-day intellectual cycle.
“Afterglow,” according to the Free AF website, refers to the brand’s “100% natural, New Zealand botanical extract from a fruit that triggers the same receptors as chocolate and chilli.”
Once it disappears, it leaves behind a counterpart at longer wavelengths (X-ray, UV, optical, infrared, and radio) known as the afterglow [3] that generally remains detectable for days or longer. In contrast to the GRB emission, the afterglow emission is not believed to be dominated by internal shocks.
GRB 970228 [2] was the first gamma-ray burst (GRB) for which an afterglow was observed. [3] It was detected on 28 February 1997 at 02:58 UTC.Since 1993, physicists had predicted GRBs to be followed by a lower-energy afterglow (in wavelengths such as radio waves, x-rays, and even visible light), but until this event, GRBs had only been observed in highly luminous bursts of high-energy gamma ...
Early searches for this afterglow were unsuccessful, largely because it is difficult to observe a burst's position at longer wavelengths immediately after the initial burst. The breakthrough came in February 1997 when the satellite BeppoSAX detected a gamma-ray burst ( GRB 970228 [ nb 2 ] ) and when the X-ray camera was pointed towards the ...
A plasma afterglow (also afterglow) is the radiation emitted from a plasma after the source of ionization is removed. [1] The external electromagnetic fields that sustained the plasma glow are absent or insufficient to maintain the discharge in the afterglow. A plasma afterglow can either be a temporal, due to an interrupted (pulsed) plasma ...
First X-ray afterglow, first optical afterglow GRB 970402: RA 14 h 50.1 m Dec −69° 20′ BeppoSAX: From an X-ray source never seen before in the constellation Circinus. [Ref 2] GRB 970508: z = 0.835: BeppoSAX: First redshift, first radio afterglow GRB 971214: z = 3.4: BATSE: The first GRB at z > 1; the most luminous of the earliest few GRBs ...
In 2010, Frontera along with Enrico Costa, [9] one of his two deputy PIs for the BeppoSAX/PDS and GRBM experiments, was awarded the SIF Enrico Fermi prize, of the Italian Physical Society, for “the discovery of the afterglow, i.e., of the X-ray luminescence, from Gamma Ray Bursts”. [33]
