New Arabic Records From Cairo on Supernovae 1181 and 1006
Astronomische Nachrichten, EarlyView.ABSTRACT The remnant of the historical supernova SN 1181 is under discussion: While the previously suggested G130.7+3.1 (3C58) appears too old (3000–5000 year), the unusual star IRAS00500+6713 with a surrounding nebula (Pa‐30) has an expansion age not inconsistent with a SN Iax explosion in ad 1181 under the assumption that neither acceleration nor ...

Astronomische Nachrichten, EarlyView.ABSTRACT We present James Webb Space Telescope observations of M 4—the closest globular cluster—that probe the lower Main Sequence down to the hydrogen‐burning limit. The unveiled stellar sequence reaches much fainter luminosities than previously possible, revealing a few extremely red objects that are consistent with brown dwarfs as cool as Teff∼1000K$

The Dependence of Globular Cluster Number on Density for Abell Cluster Central Galaxies [PDF]
, 1997 A study of the globular cluster systems of 23 brightest, or central, galaxies in 19 Abell clusters has recently been completed. This Letter presents some of the newly discovered correlations of the globular cluster specific frequency $S_N$ in these ...

Anxious Projections: Mass Hysteria and the Problem of Interpretation
Medical Anthropology Quarterly, EarlyView.Abstract Stories of “mass hysteria” among teenage girls have often graced the headlines of Nepal's local and national newspapers, creating a public spectacle of a strange and mysterious form of affliction. Treatments include both shamanic rituals and psychosocial interventions, a new therapeutic modality that has gained prominence over the past two ...

EVOLUTION OF BRIGHTEST CLUSTER GALAXY STRUCTURAL PARAMETERS IN THE LAST ∼6 Gyr: FEEDBACK PROCESSES VERSUS MERGER EVENTS [PDF]
, 2010 We present results on the evolution of the structural parameters of two samples of brightest cluster galaxies (BCGs) in the last 6 Gyr. The nearby sample of BCGs consists of 69 galaxies from the WINGS survey spanning a redshift range of 0.04 < z < 0.07 ...

A Chromosome Inversion Creates a Supergene for Sex and Colour in Lake Malawi Cichlids
Molecular Ecology, EarlyView.ABSTRACT Cichlid fishes have the highest rates of evolutionary turnover of sex chromosomes among vertebrates. Many large structural polymorphisms in the radiation of cichlids in Lake Malawi are associated with sex chromosomes and may also carry adaptive variation.

The Mass Distribution of SDSS J1004+4112 Revisited
, 2010 We present a strong lens analysis of SDSS J1004+4112, a unique quasar lens produced by a massive cluster of galaxies at z=0.68, using a newly developed software for gravitational lensing.
