Abstract:
Extragalactic radio sources are a significant contaminant in cosmic
microwave background and Sunyaev-Zel'dovich effect experiments. Deep
interferometric observations with the BIMA and OVRO arrays are used to
characterize the spatial, spectral, and flux distributions of radio
sources toward massive galaxy clusters at 28.5GHz. We compute counts
of millijansky source fluxes from 89 fields centered on known massive
galaxy clusters and 8 noncluster fields.
Description:
The 28.5GHz observations were carried out with BIMA during the summers
of 1996-2002 and OVRO during the summers of 1995-2001 as part of the
OVRO/BIMA SZE imaging project (see, e.g., Reese et al.,
2002ApJ...581...53R 2002ApJ...581...53R and Grego et al., 2001ApJ...552....2G 2001ApJ...552....2G). A total of
62 cluster fields were observed at BIMA, and 55 cluster fields were
observed at OVRO. A total of 28 cluster fields were observed at both
BIMA and OVRO, yielding observations of 89 unique cluster fields. For
the BIMA CMB fine-scale anisotropy project (Dawson et al.,
2002ApJ...581...86D 2002ApJ...581...86D, 2006, Cat. J/ApJ/647/13), a total of 18
noncluster fields were observed.

Note (1): Sources identified as [CBC2007] JHHMMSS.s+DDMMSS.s in Simbad
Note (2): Array used as follows:
B = Berkeley Illinois Maryland Association millimeter array (BIMA)
O = Owens Valley Radio Observatory (OVRO)
Note (3): Flag on S1.4 as follows:
a = No detection found in the literature. Using the 3 times the NVSS
noise level, we set an upper limit on the 1.4GHz flux of 1.35mJy
and an upper limit on the 1.4 to 28.5GHz spectral index of 0.0
b = No detection found in the literature. Using the 3 times the NVSS
noise level, we set an upper limit on the 1.4GHz flux of 1.35mJy
and an upper limit on the 1.4 to 28.5GHz spectral index of 0.0
c = FIRST catalog (Cat. VIII/71)
d = No detection found in the literature. Using the 3 times the NVSS
noise level, we set an upper limit on the 1.4GHz flux of 1.35mJy
and an upper limit on the 1.4 to 28.5GHz spectral index of 0.0
e = VLA map. Fluxes are obtained by CLEANing the images in AIPS
f = Using the 3 times the VLA map noise level, we set an upper limit
on the 1.4GHz flux of 0.45mJy and an upper limit on the 1.4 to
28.5GHz spectral index of -0.7. The source is detected at 6cm by
Partridge et al. (1986ApJ...308...46P 1986ApJ...308...46P) with a flux of 2.59mJy,
which yields a spectral index of -0.4 from 5 to 28.5GHz.
g = No detection found in the literature. Using the 3 times the VLA
map noise level, we set an upper limit on the 1.4GHz flux of
1.32mJy and an upper limit on the 1.4 to 28.5GHz spectral index
of +0.2.
h = FIRST map.
i = No detection. Using the 3 times the NVSS noise level, we set an
upper limit on the 1.4GHz flux of 1.35mJy and an upper limit on
the 1.4 to 28.5GHz spectral index of -0.4.
j = No detection. Using the 3 times the FIRST noise level, we set an
upper limit on the 1.4GHz flux of 0.45mJy and an upper limit on
the 1.4 to 28.5GHz spectral index of -0.4.
