Abstract:
Dwarf highly star-forming galaxies dominated the early Universe and
are considered the main driver of its reionization. Direct
observations of these very distant galaxies are limited mainly to
rest-frame ultraviolet and visible wavelengths, and as a result, some
of their properties are out of reach. Therefore, the study of their
local analogs, the Green Pea (GP) and Blueberry (BB) galaxies is still
of paramount importance. This work aims to expand the number of known
BBs to smaller distances and the south equatorial sky. In addition to
the already known, this new sample of BBs allows for a statistically
significant study of their properties probed by visible and infrared
(IR) light. We utilize HECATE, a catalog of galaxies up to 200Mpc,
which provides optical/IR photometry and characterization of the
sources. To select and analyze the sample, we adopt the Pan-STARSS and
SDSS optical photometries, and MPA-JHU analysis for sources having
spectroscopic observations. Benefited by the multiwavelength coverage,
we perform spectral energy distribution fitting to provide homogeneous
star-formation rates and stellar masses. The selected BBs are compared
with GPs and other dwarf star- forming galaxies (SFGs). This work has
identified 48 BBs out of which 40 are newly discovered. The nearest BB
lies at 19Mpc while 14 BBs are in the south equatorial sky. The BBs
tend to be extremely IR red in both WISE W1-W2 and W2-W3 colors,
located in different positions in this diagram compared to typical
SFGs. Overall, dwarf SFGs with higher specific star-formation rates
tend to have redder IR colors. Although GPs and BBs share many
similarities, the latter are the most intensively star-forming sources
of the local Universe among dwarf galaxies. Overall BBs are
intrinsically bluer in visible light, redder in the IR, less massive,
have higher specific star-formation rates and equivalent widths, lower
metallicities, and have the most strongly ionized interstellar medium
compared to typical SFGs and GPs.
Description:
table23.dat combines Tables 2, and 3 shown in the paper. It also
includes alternative SFR, and stellar mass measurements by MPA-JHU and
HECATE, and the emission-line fluxes measured with FADO.
Table 2: The observed g-r, and r-i colors of the BBs of this work from
the different photometries. The sources are arranged in ascending order
based on their weighted average g-r color.
Table 3: Redshift, distances, sizes, stellar masses, sSFR,
metallicities, EWs, and the HeII lambda4684 of the proposed BBs.
