“…Conversely, the line profile of the SMG is asymmetric and broader than that of the quasar. It was fit with a combination of two Gaussians with the fainter component fixed at 250 km s −1 , as suggested by Salomé et al (2012) and explained in more detail below. The results, including average velocities and velocity dispersions, are presented in Table 1.…”

“…For the QSO the width of the second component is fixed to that of the main component. For the SMG, the velocity of the fainter component is fixed at 250 km s −1 (Salomé et al 2012). the QSO (Fig. 1) is detected in the continuum at the ∼8σ level (σ = 0.2 mJy beam −1 ).…”

“…Moreover, the system has been found to be more complex than previously thought. Wagg et al (2012) and Carilli et al (2013) detected two fainter sources, one southwest of the quasar and one in between the QSO and the SMG, which are the [CII] counterparts of known Lyα emitters; furthermore, the CO line profile and position-velocity diagram by Salomé et al (2012) indicate a close companion also for the SMG. Intriguingly, the CO position-velocity diagrams for both the QSO and the SMG suggest that the two galaxies have regularly rotating disks.…”

We performed a kinematical analysis of the [CII] line emission of the BR 1202-0725 system at z ∼ 4.7 using ALMA science verification observations. The most prominent sources of this system are a quasar (QSO) and a submillimeter galaxy (SMG), separated by a projected distance of about ∼24 kpc and characterized by very high star formation rates, higher than ∼1000 M yr −1 . However, the ALMA observations reveal that these galaxies apparently have undisturbed rotating disks, which is at variance with the commonly accepted scenario in which strong star formation activity is induced by a major merger. We also detected faint components which, after spectral deblending, were spatially resolved from the main QSO and SMG emissions. The relative velocities and positions of these components are compatible with orbital motions within the gravitational potentials generated by the QSO host galaxy and the SMG, suggesting that they are smaller galaxies in interaction or gas clouds in accretion flows of tidal streams. Moreover, we did not find any clear spectral evidence for outflows caused by active galactic nuclei or stellar feedback. This suggests that the high star formation rates might be induced by interactions or minor mergers with these companions, which do not affect the large-scale kinematics of the disks, however. Alternatively, the strong star formation may be fueled by the accretion of pristine gas from the host halo. Our kinematical analysis also indicates that the QSO and the SMG have similar dynamical masses, mostly in the form of molecular gas, and that the QSO host galaxy and the SMG are seen close to face-on with slightly different disk inclinations: the QSO host galaxy is seen almost face-on (i ∼ 15 • ), while the SMG is seen at higher inclinations (i ∼ 25 • ). Finally, the ratio between the black hole mass of the QSO, obtained from new X-shooter spectroscopy, and the dynamical mass of the host galaxy is similar to value found in very massive local galaxies, suggesting that the evolution of black hole galaxy relations is probably better studied with dynamical than with stellar host galaxy masses.

“…It is thus no surprise that most high-z close mergers (10 kpc projected separation) have been discovered through the gravitational lensing effect (e.g., Ivison et al 2010b;MacKenzie et al 2014;Messias et al 2014;Rawle et al 2014;Wuyts et al 2014;Spilker et al 2015;Marrone et al 2018), with a few exceptions of unlensed, well separated, SMG-SMG, SMG-QSO or SMG-LBG bright interacting pairs resolved with interferometric observations (e.g., Ivison et al 2002Ivison et al , 2008Smail et al 2003;Salomé et al 2012;Oteo et al 2016;Lu et al 2017;Riechers et al 2017). …”

AbstractThe submillimeter galaxy (SMG) HERMES J105751.1+573027 (hereafter HLock01) at z=2.9574±0.0001 is one of the brightest gravitationally lensed sources discovered in the Herschel Multi-tiered Extragalactic Survey. Apart from the high flux densities in the far-infrared, it is also extremely bright in the rest-frame ultraviolet (UV), with a total apparent magnitude m UV ;19.7 mag. We report here deep spectroscopic observations with the Gran Telescopio Canarias of the optically bright lensed images of HLock01. Our results suggest that HLock01 is a merger system composed of the Herschel-selected SMG and an optically bright Lyman break-like galaxy (LBG), separated by only 3.3 kpc in projection. While the SMG appears very massive(M * ;5×10 11 M e ), with a highly extinguished stellar component (A V ;4.3 ), the LBG is a young, lower-mass (M * ;1×10 10 M e ), but still luminous ( L 10 UV * ) satellite galaxy. Detailed analysis of the high signal-to-noise ratio (S/N) rest-frame UV spectrum of the LBG shows complex kinematics of the gas, exhibiting both blueshifted and redshifted absorption components. While the blueshifted component is associated with strong galactic outflows from the massive stars in the LBG, as is common in most star-forming galaxies, the redshifted component may be associated with gas inflow seen along a favorable sightline to the LBG. We also find evidence of an extended gas reservoir around HLock01 at an impact parameter of 110 kpc, through the detection of C II λλ1334 absorption in the red wing of a bright Lyα emitter at z;3.327. The data presented here highlight the power of gravitational lensing in high S/N studies to probe deeply into the physics of high-z star-forming galaxies.
