“…Furthermore, the S4TM strong-lens sample can be a useful resource for testing GR by comparing dynamical mass and lensing mass (e.g., Bolton et al 2006b;Jain & Zhang 2008;Schwab et al 2010;Cao et al 2017). In particular, the extended mass coverage of the S4TM sample will provide extra constraints on GR by revealing the environmental dependence of dark-matter halo properties as demonstrated by the numerical simulations (e.g., Zhao et al 2011;Winther et al 2012;He et al 2014). Lastly, we note that by further going to candidates with lower predicted lensing cross sections, Table 2 Strong-lens Model Parameters of the 40 S4TM Grade-A Lenses Note.…”

We present the full sample of 118 galaxy-scale strong-lens candidates in the Sloan Lens ACS (SLACS) Survey for the Masses (S4TM) Survey, which are spectroscopically selected from the final data release of the Sloan Digital Sky Survey. Follow-up Hubble Space Telescope (HST) imaging observations confirm that 40 candidates are definite strong lenses with multiple lensed images. The foreground-lens galaxies are found to be early-type galaxies (ETGs) at redshifts 0.06-0.44, and background sources are emission-line galaxies at redshifts 0.22-1.29. As an extension of the SLACS Survey, the S4TM Survey is the first attempt to preferentially search for strong-lens systems with relatively lower lens masses than those in the pre-existing strong-lens samples. By fitting HST data with a singular isothermal ellipsoid model, we find that the total projected mass within the Einstein radius of the S4TM strong-lens sample ranges from 3×1010 M e to 2×10 11 M e . In Shu et al., we have derived the total stellar mass of the S4TM lenses to be 5×1010 M e to 1×10 12 M e . Both the total enclosed mass and stellar mass of the S4TM lenses are on average almost a factor of 2 smaller than those of the SLACS lenses, which also represent the typical mass scales of the current strong-lens samples. The extended mass coverage provided by the S4TM sample can enable a direct test, with the aid of strong lensing, for transitions in scaling relations, kinematic properties, mass structure, and dark-matter content trends of ETGs at intermediate-mass scales as noted in previous studies.

“…Therefore, the study of their properties is of great importance to the understanding of the fundamental nature of gravity. A number of halo properties have been studied in detail in the context of f(R) gravity, such as the angular momentum, spin, velocity dispersion (Lee et al 2013;He et al 2015), velocity profile (Gronke et al 2015) and screening (Zhao, Li & Koyama 2011a;Li, Zhao & Koyama 2012b;He et al 2014). The improved resolution of our simulations enables us to study a wider range of the physical properties of haloes.…”

Beyond the cosmological standard model

et al. 2015

After a decade and a half of research motivated by the accelerating universe, theory and experiment have a reached a certain level of maturity. The development of theoretical models beyond Λ or smooth dark energy, often called modified gravity, has led to broader insights into a path forward, and a host of observational and experimental tests have been developed. In this review we present the current state of the field and describe a framework for anticipating developments in the next decade. We identify the guiding principles for rigorous and consistent modifications of the standard model, and discuss the prospects for empirical tests.We begin by reviewing recent attempts to consistently modify Einstein gravity in the infrared, focusing on the notion that additional degrees of freedom introduced by the modification must "screen" themselves from local tests of gravity. We categorize screening mechanisms into three broad classes: mechanisms which become active in regions of high Newtonian potential, those in which first derivatives of the field become important, and those for which second derivatives of the field are important. Examples of the first class, such as f (R) gravity, employ the familiar chameleon or symmetron mechanisms, whereas examples of the last class are galileon and massive gravity theories, employing the Vainshtein mechanism. In each case, we describe the theories as effective theories and discuss prospects for completion in a more fundamental theory. We describe experimental tests of each class of theories, summarizing laboratory and solar system tests and describing in some detail astrophysical and cosmological tests. Finally, we discuss prospects for future tests which will be sensitive to different signatures of new physics in the gravitational sector.The review is structured so that those parts that are more relevant to theorists vs. observers/experimentalists are clearly indicated, in the hope that this will serve as a useful reference for both audiences, as well as helping those interested in bridging the gap between them.
