“…For the remaining two clusters being analyzed in this work, we have data for RCS 2327 as part of the SURFS UP HST observations (HST-GO13177 PI Bradač; Hoag et al 2015) and previous archival data (HST-GO10846 PI Gladders; see also Sharon et al 2015).

We study the stellar population properties of the IRAC-detected 6  z  10 galaxy candidates from the Spitzer UltRa Faint SUrvey Program. Using the Lyman Break selection technique, we find a total of 17 galaxy candidates at 6  z  10 from Hubble Space Telescope images (including the full-depth images from the Hubble Frontier Fields program for MACS 1149 and MACS 0717) that have detections at signal-to-noise ratios  3 in at least one of the IRAC 3.6 and 4.5 μm channels. According to the best mass models available for the surveyed galaxy clusters, these IRAC-detected galaxy candidates are magnified by factors of ∼1.2-5.5. Due to the magnification of the foreground galaxy clusters, the rest-frame UV absolute magnitudes M 1600 are between −21.2 and −18.9 mag, while their intrinsic stellar masses are between 2×10 8 M e and 2.9×10 9 M e . We identify two Lyα emitters in our sample from the Keck DEIMOS spectra, one at z Lyα =6.76 (in RXJ 1347) and one at z Lyα =6.32 (in MACS 0454). We find that 4 out of 17 z  6 galaxy candidates are favored by z  1 solutions when IRAC fluxes are included in photometric redshift fitting. We also show that IRAC [3.6]-[4.5] color, when combined with photometric redshift, can be used to identify galaxies which likely have strong nebular emission lines or obscured active galactic nucleus contributions within certain redshift windows.

“…These include the largest known gravitational lens, MACS J0717.5+3745, included also in the Cluster Lensing And Supernova with Hubble (CLASH; Postman et al 2012) and Hubble Frontier Fields (HFF; Lotz et al 2016) programs, with θ E ∼ 55 (Zitrin et al 2009a); Abell 1689 (θ E ∼ 45 , Broadhurst et al 2005); and the HFF cluster Abell 370 (∼ 40 , Richard et al 2010). Worth mentioning is also RCS2 J232727.6-020437, for which Sharon et al (2015) find θ E 40 for z s 3 (but smaller -i.e. 26 -as expected, for another source at z 1.4).…”

Since galaxy clusters sit at the high-end of the mass function, the number of galaxy clusters both massive and concentrated enough to yield particularly large Einstein radii poses useful constraints on cosmological and structure formation models. To date, less than a handful of clusters are known to have Einstein radii exceeding ∼ 40 (for a source at z s 2, nominally). Here, we report an addition to that list of the Sunyaev-Zel'dovich (SZ) selected cluster, PLCK G287.0+32.9 (z = 0.38), the second-highest SZ-mass (M 500 ) cluster from the Planck catalog. We present the first strong lensing analysis of the cluster, identifying 20 sets of multiply-imaged galaxies and candidates in new Hubble Space Telescope data, including a long, l ∼ 22 giant arc, as well as a quadruply-imaged, apparently bright (magnified to J F 110W =25.3 AB), likely high-redshift dropout galaxy at z phot = 6.90 [6.13-8.43] (95% C.I.). Our analysis reveals a very large critical area (1.55 arcmin 2 , z s 2), corresponding to an effective Einstein radius of θ E ∼ 42 . The model suggests the critical area will expand to 2.58 arcmin 2 (θ E ∼ 54 ) for sources at z s ∼ 10. Our work adds to recent efforts to model very massive clusters towards the launch of the James Webb Space Telescope, in order to identify the most useful cosmic lenses for studying the early Universe. Spectroscopic redshifts for the multiply-imaged galaxies and additional HST data will be necessary for refining the lens model and verifying the nature of the z ∼ 7 dropout.

“…For example, only few out of the 25 X-ray selected CLASH clusters have Einstein radii comparable to, or slightly larger than that of MACS2135, and only a few clusters previously analyzed have considerably larger critical areas, e.g., Abell 1703, (Limousin et al 2008); MACS 0717 (Zitrin et al 2009a); RXJ1347 ;Abell 1689 (Broadhurst et al 2005); A370 (Richard et al 2010); RCS2 J232727.6-020437, (Sharon et al 2015); SDSS J120923.7+264047 (Ofek et al 2008); or CL0024 (Zitrin et al 2009b). Indeed, thanks to their large critical areas, all of these clusters show numerous multiplyimaged background galaxies, typically revealed in deep HST imaging.…”

We present a light-traces-mass (LTM) strong-lensing model of the massive lensing cluster MACS J2135.2-0102 (z=0.33; hereafter MACS2135), known in part for hosting the cosmic eye galaxy lens. MACS2135 is also known to multiplylens a z=2.3 sub-millimeter galaxy near the brightest cluster galaxy (BCG), as well as a prominent, triply imaged system at a large radius of ∼37″ south of the BCG. We use the latest available Hubble imaging to construct an accurate lensing model for this cluster, identifying six new multiplyimaged systems with the guidance of our LTM method, so that we have roughly quadrupled the number of lensing constraints. We determine that MACS2135 is among the top lensing clusters known, comparable in size to the . We make our lens model, including mass and magnification maps, publicly available, in anticipation of searches for high-z galaxies with the James Webb Space Telescope, for which this cluster is a compelling target.
