  • Interesting fact: The world's deadliest mushroom is the Amanita phalloides, the death cap. The five different poisons contained by the mushroom cause diarrhea and vomiting within 6 to 12 hours of ingestion. This is followed by damage to the liver, kidneys, and central nervous system and, in the majority of cases, coma and death.
    • n Coma kō"mȧ A state of profound insensibility from which it is difficult or impossible to rouse a person. See Carus.

In science:

Using the newly obtained data we re-determine the UV luminosity function of Coma and we compute for the first time the UV luminosity function of A1367.
Optical spectroscopy and the UV luminosity function of galaxies in the Abell 1367, Coma and Virgo clusters
Iglesias-Paramo et al. (2002) carried out a deep Hα imaging survey of 1 × 1 degree area in Coma and A1367 clusters and obtained the first Hα luminosity function of nearby clusters of galaxies.
Optical spectroscopy and the UV luminosity function of galaxies in the Abell 1367, Coma and Virgo clusters
As a side product we also obtained redshifts of several UV selected galaxies in Coma and A1367 regions which enable us to re-compute the UV luminosity functions of the two clusters.
Optical spectroscopy and the UV luminosity function of galaxies in the Abell 1367, Coma and Virgo clusters
The Hα and UV luminosity functions of A1367 and Coma are discussed in Section 5.
Optical spectroscopy and the UV luminosity function of galaxies in the Abell 1367, Coma and Virgo clusters
The Hα selected galaxies in the Coma cluster were all spectroscopically measured, while only 75% of them were observed in A1367.
Optical spectroscopy and the UV luminosity function of galaxies in the Abell 1367, Coma and Virgo clusters
Including the present observations, spectra are available for 64% and 56% of the UV selected galaxies with an optical counterpart in A1367 and Coma respectively.
Optical spectroscopy and the UV luminosity function of galaxies in the Abell 1367, Coma and Virgo clusters
With the new data presented in this work, the redshift of all Hα selected galaxies in the Coma cluster (Iglesias-Paramo et al. (2002)) have been measured.
Optical spectroscopy and the UV luminosity function of galaxies in the Abell 1367, Coma and Virgo clusters
The Hα luminosity function determined by Iglesias-Paramo et al. (2002) assuming that all ob jects were at the distance of Coma is fully confirmed.

Redshift completeness of the UV selected galaxies in Coma (dotted histogram) and A1367 (long dashed histogram).
Optical spectroscopy and the UV luminosity function of galaxies in the Abell 1367, Coma and Virgo clusters
The Hα luminosity functions of Coma and A1367 are found consistent one another, being characterized by a faint end slope α∼-0.7.
Optical spectroscopy and the UV luminosity function of galaxies in the Abell 1367, Coma and Virgo clusters
This value differs significantly from the slope of the UV luminosity function of Coma (Andreon 1999, hereafter A99) α∼-2.0, the only UV luminosity function ever determined for a cluster.
Optical spectroscopy and the UV luminosity function of galaxies in the Abell 1367, Coma and Virgo clusters
Thus we use the spectroscopic observations presented in this work to re-compute the Coma UV luminosity function and to compute, for the first time, the UV luminosity function of A1367.
Optical spectroscopy and the UV luminosity function of galaxies in the Abell 1367, Coma and Virgo clusters
Integrated UV galaxy counts in the field by Milliard et al. 1992 (solid line), upper and lower background limits for Coma (dotted line) and for A1367 (long dashed line) are given.

The UV luminosity functions of the Coma galaxies.
Optical spectroscopy and the UV luminosity function of galaxies in the Abell 1367, Coma and Virgo clusters
The over-density of UV counts due to Coma/A1367 galaxies can be derived from the difference between the counts in the direction of the two clusters and the UV galaxy counts derived in three random fields by Milliard et al. (1992) using the same experimental set up as for Coma and A1367.
