Hipass Detection of an Intergalactic Gas Cloud in the Ngc 2442 Group
We report the discovery, from the H I Parkes All-Sky Survey (HIPASS), of a gas cloud associated with the asymmetric spiral galaxy NGC 2442. This object, designated HIPASS J0731–69, contains ∼ 10 M⊙ of H I, or nearly one-third as much atomic gas as NGC 2442 itself. No optical counterpart to any part of HIPASS J0731–69 has yet been identified, consistent with the gas being diffuse, and with its s...
متن کاملLyman Absorption and Tidal Debris
It is suggested that a signi cant fraction of the low column-density absorption features seen in the spectra of quasars are produced in pressure-con ned tidal debris, that was built up in small groups and clusters of galaxies over a Hubble time. We show that the space-density and cross-section of tidal tails in groups of galaxies are large enough that they could constitute a major source of the...
متن کاملRapid Dissipation of Primordial Gas from the Au Microscopii Debris Disk
The disk around AU Microscopii, an M1 star in the β Pictoris Moving Group, is extraordinarily wellsuited for comparison to the β Pic debris disk (type A5V). We use far-UV absorption spectroscopy of AU Mic to probe its edge-on disk for small amounts of H2, the primary constituent of gas giant planets. Our conservative upper limit on the line-of-sight H2 column density is 1.7 × 10 19 cm, which is...
متن کاملSignatures of Λcdm Substructure in Tidal Debris
In the past decade, surveys of the stellar component of the Galaxy have revealed a number of streams from tidally disrupted dwarf galaxies and globular clusters. Simulations of hierarchical structure formation in ΛCDM cosmologies predict that the dark matter halo of a galaxy like the Milky Way contains hundreds of subhalos with masses of ∼ 10 M⊙ and greater, and it has been suggested that the e...
متن کاملTidal Debris posing as Dark Galaxies
Debris sent into the intergalactic medium during tidal collisions has received much attention as it can tell us about several fundamental properties of galaxies, in particular their missing mass, both in the form of cosmological Dark Matter and so-called Lost Baryons. High velocity encounters, which are common in clusters of galaxies, are able to produce faint tidal debris that may appear as st...
