The role of children in the traditional religious house-blessing rite of Salpassa in north-eastern Spain

Salpassa denotes the blessing of houses, land, and other belongings, carried out during Easter week and Resurrection (Easter) Sunday in the Valencia–Catalonia linguistic region of north-eastern Spain. Although it is now remembered mostly as a consecrating ceremony or a religious rite, recent field research has shown that a playful element, carried out by children through their songs and other activities, was also an important aspect of the traditional Salpassa.

The X-ray quiescence of Swift J195509.6+261406 (GRB 070610): an optical bursting X-ray binary?

We report on an ~63 ks Chandra observation of the X-ray transient Swift J195509.6+261406 discovered as the afterglow of what was first believed to be a long-duration gamma-ray burst (GRB 070610). The outburst of this source was characterized by unique optical flares on timescales of second or less, morphologically similar to the short X-ray bursts usually observed from magnetars. Our Chandra observation was performed ~2 years after the discovery of the optical and X-ray flaring activity of this source, catching it in its quiescent state. We derive stringent upper limits on the quiescent emission of Swift J195509.6+261406, which argues against the possibility of this object being a typical magnetar. Our limits show that the most viable interpretation on the nature of this peculiar bursting source is a binary system hosting a black hole or a neutron star with a low-mass companion star (<0.12 M ☉) and with an orbital period smaller than a few hours.
