Telescope Array Bursts, Radio Pulses and Axion Quark Nuggets

Abstract

Telescope Array (TA) experiment has recorded [1,2] several short time bursts of air shower like events. These bursts are very distinct from conventional single showers, and are found to be strongly correlated with lightnings. In our previous work [3] we proposed that these bursts represent the direct manifestation of the dark matter annihilation events within the so-called axion quark nugget (AQN) model. In the present work we suggest to test this proposal to search for the radio signals in frequency band ν ∈ (0.5 − 200) MHz which must be synchronized with the TA bursts.

Multi-Modal Clustering Events observed by Horizon-10T and Axion Quark Nuggets

“…We estimated the event rates for three dramatically different puzzling CR-like events: for mysterious TA bursts [9], for the ANITA anomalous events [13], and finally for the Multi-Modal Events in this work as estimated in (16). All three puzzling phenomena are proportional to one and the same AQN flux (10). The self-consistency between all three estimates hints on a common nature for these puzzling CR-like events.…”

“…Therefore, the estimated energy from individual events within the bursts is five to six orders of magnitude higher than the energy estimated by event rate [11,12]. It has been argued in [9,10] that these bursts represent the direct manifestation of the AQN annihilation events. This feature, in many aspects, is very similar to the intensity puzzle listed in previous Section II, where analogous dramatic inconsistency (between the observed intensity and measured event rate) is recorded by H10T instrument.…”

“…First, as we already mentioned the parameters entering (10) are in fact not precisely known. The fundamental parameters such as ρ DM and v AQN only have accuracy up to order one as the local flux distribution of DM and size distribution of AQN remain unknown to date as the DM density locally may dramatically deviate from the well established average global value ρ DM ≈ 0.3 GeV cm −3 , see introduction in [54] for the references and details.…”

Furthermore, the size distribution factor entering (10) in form B −1 had been fixed from dramatically different physics (including solar corona heating puzzle) and can easily deviate by large factor. The estimation of the effective area A eff also suffers enormous uncertainty.…”

“…One should mention here that a similar conclusion has been also reached for a different type of unusual CR-like events. First, it has been argued in [9,10] that the Telescope Array (TA) "mysterious bursts" [11,12] can be naturally interpreted as the AQN events. Secondly, it has been also argued in [13] that the Antarctic Impulse Transient Antenna (ANITA) observation [14][15][16] of two anomalous events with noninverted polarity might be also a consequence of the AQN annihilation events.…”
