A Tangle of Stellar Streams in the North Galactic Cap

A Tangle of Stellar Streams in the North Galactic Cap

Stellar halo substructures were identified using statistical photometric parallax of blue main-sequence turnoff stars from 14 Sloan Digital Sky Survey stripes in the north Galactic cap. Four structures are consistent with previous measurements of the Sagittarius dwarf tidal stream: the leading tail,...

description Stellar halo substructures were identified using statistical photometric parallax of blue main-sequence turnoff stars from 14 Sloan Digital Sky Survey stripes in the north Galactic cap. Four structures are consistent with previous measurements of the Sagittarius dwarf tidal stream: the leading tail, the "bifurcated" stream, the trailing tail, and Stream C. The stellar overdensity in Virgo, about 15 kpc from the Sun, could arise from the crossing of the Parallel Stream and a new, candidate stream dubbed the Perpendicular Stream. The data suggests the presence of a wide stream near NGC 5466, with a distance of 5-15 kpc. Measurements of the flattening of the smooth stellar halo from the 14 stripes average q = 0.58, with a dispersion of 0.04.
