HectoMAP and Horizon Run 4: Dense Structures and Voids in the Real and Simulated Universe
Ho Seong Hwang, Margaret J. Geller, Changbom Park +10
HectoMAP is a dense redshift survey of red galaxies covering a 53 strip of the northern sky. HectoMAP is 97\% complete for galaxies with , , and $(r-i)…
A Redshift Survey of the Strong Lensing Cluster Abell 383
Margaret J. Geller, Ho Seong Hwang, Antonaldo Diaferio +3
Abell 383 is a famous rich cluster (z = 0.1887) imaged extensively as a basis for intensive strong and weak lensing studies. Nonetheless there are few spectroscopic observations. W…
The Chemical Evolution of Star-Forming Galaxies Over the Last 11 Billion Years
H. Jabran Zahid, Margaret Geller, Lisa Kewley +3
We calculate the stellar mass-metallicity relation at five epochs ranging to z~2.3. We quantify evolution in the shape of the mass-metallicity relation as a function of redshift; t…
Measuring the Ultimate Mass of Galaxy Clusters: Redshifts and Mass Profiles from the Hectospec Cluster Survey (HeCS)
Kenneth Rines, Margaret J. Geller, Antonaldo Diaferio +1
The infall regions of galaxy clusters represent the largest gravitationally bound structures in a CDM universe. Measuring cluster mass profiles into the infall regions provides…
SHELS: Optical Spectral Properties of WISE 22 μm-selected Galaxies
Ho Seong Hwang, Margaret J. Geller, Michael J. Kurtz +2
We use a dense, complete redshift survey, the Smithsonian Hectospec Lensing Survey (SHELS), covering a 4 square degree region of a deep imaging survey, the Deep Lens Survey (DLS),…
CLASH: Precise New Constraints on the Mass Profile of Abell 2261
Dan Coe, Keiichi Umetsu, Adi Zitrin +43
We precisely constrain the inner mass profile of Abell 2261 (z=0.225) for the first time and determine this cluster is not "over-concentrated" as found previously, implying a forma…
Mapping the Universe: The 2010 Russell Lecture
Margaret J. Geller, Antonaldo Diaferio, Michael J. Kurtz
Redshift surveys are a powerful tool of modern cosmology. We discuss two aspects of their power to map the distribution of mass and light in the universe: (1) measuring the mass di…
The Faint End of the Luminosity Function and Low Surface Brightness Galaxies
Margaret J. Geller, Antonaldo Diaferio, Michael J. Kurtz +2
SHELS (Smithsonian Hectospec Lensing Survey) is a dense redshift survey covering a 4 square degree region to a limiting R = 20.6. In the construction of the galaxy catalog and in t…
Testing Weak Lensing Maps With Redshift Surveys: A Subaru Field
Michael J. Kurtz, Margaret J. Geller, Yousuke Utsumi +3
We use a dense redshift survey in the foreground of the Subaru GTO2deg^2 weak lensing field (centered at = 16; =43^\circ11^{\prime}24^{\prime\prime…
Empirical optical k-Corrections for redshifts <= 0.7
Eduard Westra, Margaret J. Geller, Michael J. Kurtz +2
The Smithsonian Hectospec Lensing Survey (SHELS) is a magnitude limited spectroscopically complete survey for R<=21.0 covering 4 square degrees. SHELS provides a large sample (15,5…
Triggered Star Formation in Galaxy Pairs at z=0.08-0.38
Deborah Freedman Woods, Margaret J. Geller, Michael J. Kurtz +3
We measure the strength, frequency, and timescale of tidally triggered star formation at redshift z=0.08-0.38 in a spectroscopically complete sample of galaxy pairs drawn from the…
SHELS: Testing Weak Lensing Maps with Redshift Surveys
Margaret J. Geller, Michael J. Kurtz, Ian P. Dell'Antonio +2
Weak lensing surveys are emerging as an important tool for the construction of "mass selected" clusters of galaxies. We evaluate both the efficiency and completeness of a weak lens…
Evolution of the Halpha luminosity function
Eduard Westra, Margaret J. Geller, Michael J. Kurtz +2
The Smithsonian Hectospec Lensing Survey (SHELS) is a window on the star formation history over the last 4 Gyr. SHELS is a spectroscopically complete survey for Rtot < 20.3 over 4…
