The alignment of galaxy spin with the shear field in observations
Isha Pahwa, Noam I. Libeskind, Elmo Tempel +6
Tidal torque theory suggests that galaxies gain angular momentum in the linear stage of structure formation. Such a theory predicts alignments between the spin of haloes and tidal…
Globular Cluster Populations: Results Including SG Late-Type Galaxies
Dennis Zaritsky, Kelsey McCabe, Manuel Aravena +18
Using 3.6 and 4.5m images of 73 late-type, edge-on galaxies from the SG survey, we compare the richness of the globular cluster populations of these galaxies to those of ear…
Cosmicflows Constrained Local UniversE Simulations
Jenny G. Sorce, Stefan Gottloeber, Gustavo Yepes +6
This paper combines observational datasets and cosmological simulations to generate realistic numerical replicas of the nearby Universe. These latter are excellent laboratories for…
The Low Redshift survey at Calar Alto (LoRCA)
J. Comparat, C. -H. Chuang, S. Rodriguez-Torres +13
The Baryon Acoustic Oscillation (BAO) feature in the power spectrum of galaxies provides a standard ruler to measure the accelerated expansion of the Universe. To extract all avail…
The Arrowhead Mini-Supercluster of Galaxies
Daniel Pomarede, R. Brent Tully, Yehuda Hoffman +1
Superclusters of galaxies can be defined kinematically from local evaluations of the velocity shear tensor. The location where the smallest eigenvalue of the shear is positive and…
Filaments from the galaxy distribution and from the velocity field in the local universe
Noam I. Libeskind, Elmo Tempel, Yehuda Hoffman +2
The cosmic web that characterizes the large-scale structure of the Universe can be quantified by a variety of methods. For example, large redshift surveys can be used in combinatio…
