Research over the past decade has shown diminishing empirical evidence for major galaxy mergers being a dominating or even important mechanism growth of supermassive black holes in galaxies and triggering optically X-ray selected active galactic nuclei (AGN). We here first time test whether such connection exists at least most plausible part parameter space this mechanism: highest specific accretion rate broad-line AGNs peak epoch hole activity around z = 2. To that end we examine 21 hosting...
Abstract The James Webb Space Telescope (JWST) North Ecliptic Pole (NEP) Time-domain Field (TDF) is a >14′ diameter field optimized for multiwavelength time-domain science with JWST. It has been observed across the electromagnetic spectrum both from ground and space, including Hubble (HST). As part of HST observations over three cycles (the “TREASUREHUNT” program), deep images were obtained Wide Camera on Advanced Surveys in F435W F606W that cover almost entire JWST NEP TDF. Many...
We report on a Hubble Space Telescope search for rest-frame ultraviolet emission from the host galaxies of five far-infrared-luminous $z\simeq{}6$ quasars and $z=5.85$ hot-dust free quasar SDSS J0005-0006. perform 2D surface brightness modeling each using Markov-Chain Monte-Carlo estimator, to simultaneously fit subtract point source in order constrain underlying galaxy emission. measure upper limits $m_J>22.7$ mag $m_H>22.4$ mag, corresponding stellar masses $M_\ast<2\times10^{11}M_\odot$....
The JWST North Ecliptic Pole (NEP) Time Domain Field (TDF) is a $>$14 arcmin diameter field optimized for multi-wavelength time-domain science with JWST. Its location within JWST's northern continuous viewing zone offers optimal conditions studies JWST, ensuring year-round observability, absence of bright stars, and minimal Zodiacal foreground interference. It has been observed across the electromagnetic spectrum both from ground space, including Hubble Space Telescope (HST). As part HST...
We study the environment of z=6.33 ultraluminous quasar SDSS J010013.02+280225.8 (J0100) to understand its association with large-scale structure. Theoretical models propose high-redshift quasars as markers galaxy overdensities residing in most massive dark matter halos (DMHs) early universe. J0100 is an black hole known at z>6, suggesting a high likelihood DMH. present wide-field ($\sim$522 square arcminute) imaging r-, i-, and z-bands from Large Binocular Camera on Telescope, Y- J-band...
Abstract We study the environment of z = 6.33 ultraluminous quasar SDSS J010013.02+280225.8 (J0100) to understand its association with large-scale structure. Theoretical models propose high-redshift quasars as markers galaxy overdensities residing in most massive dark matter halos (DMHs) early Universe.
