A search for optical bursts from the rotating radio transient J1819–1458 with ULTRACAM
We report on the search for optical bursts from J1819–1458, a member of the recently discovered Rotating Radio Transients (RRATs). J1819–1458 exhibits 3 millisecond bursts with a peak flux of f ν = 3.6 Jy every ∼ 3.4 minutes, implying that it is visible for only ∼ 1 second per day at radio wavelengths. Assuming that the optical light behaves in a similar manner, the most sensitive way of detect...
متن کاملRadio polarization measurements from RRAT J1819−1458
We present the first polarization measurements of the radio emission from RRAT J1819−1458. Our observations, conducted in parallel to regular timing sessions, have yielded a small number of bright and polarized pulses. The polarization characteristics and integrated profile resemble those of normal pulsars with average spin-down energy Ė: moderate to low linear polarization in the integrated pr...
متن کاملDiscovery of Pulsations and a Possible Spectral Feature in the X-ray Emission from Rotating Radio Transient J1819–1458
PSR J1819–1458 is a rotating radio transient (RRAT) source with an inferred surface dipole magnetic field strength of 5×1013 G and a 4.26-s spin period. We present XMM-Newton observations of the X-ray counterpart of this source, CXOU J181939.1–145804, in which we identify pulsations and a possible spectral feature. The X-ray pulsations are at the period predicted by the radio ephemeris, providi...
متن کاملDiscovery of the X - Ray Counterpart to the Rotating Radio Transient
We present the discovery of the first X-ray counterpart to a Rotating RAdio Transient (RRAT) source. RRAT J1819–1458 is a relatively highly magnetized (B ∼ 5 × 1013 G) member of a new class of unusual pulsar-like objects discovered by their bursting activity at radio wavelengths. The position of RRAT J1819– 1458 was serendipitously observed by the Chandra ACIS-I camera in 2005 May. At that posi...

We derive the second and most stringent limit to date of the X-ray/radio flux ratio (FX/F1.4GHz) for the radio bursts associated with the recently identified source class, the Rotating Radio Transients (RRATs). We analyze 20.1 hr of RXTE/PCA observations of RRAT J1819−1458 – a period during which 350±23 RRAT radio bursts occurred, based on the previously observed average radio burst rate. No X-...
