Exploring Reionization-era Quasars. III. Discovery of 16 Quasars at 6.4 ≲ z ≲ 6.9 with DESI Legacy Imaging Surveys and the UKIRT Hemisphere Survey and Quasar Luminosity Function at z ∼ 6.7 [PDF]

Astrophysical Journal, 2018
This is the third paper in a series aimed at finding reionization-era quasars with the combination of DESI Legacy imaging Surveys (DELS), the Pan-STARRS1 (PS1) Survey, and near-infrared imaging surveys, such as the UKIRT Hemisphere Survey (UHS), as well ...

Luminous Quasars Do Not Live in the Most Overdense Regions of Galaxies at z~4

, 2017
We present the cross-correlation between 151 luminous quasars ($M_{ \mathrm{UV}} < -26$) and 179 protocluster candidates at $z \sim 3.8$, extracted from the Wide imaging survey ($ \sim 121~ $deg$^2$) performed with a part of the Hyper Suprime-Cam Subaru ...

Dimensional association between ADHD traits and gray matter volume in young adults: A voxel‐based morphometry study

Psychiatry and Clinical Neurosciences Reports, Volume 5, Issue 2, June 2026.
This study examined the association between attention‐deficit/hyperactivity disorder (ADHD) traits and gray matter volume (GMV) in 534 healthy young adults. Higher Hyperactivity/Restlessness scores were associated with greater GMV in the right dorsolateral prefrontal cortex (DLPFC), a region implicated in executive control and behavioral regulation. No

Predicting the Yields of z > 6.5 Quasar Surveys in the Era of Roman and Rubin

The Astrophysical Journal, 2023
About 70 luminous quasars discovered at z > 6.5 are strongly biased toward the bright end, thus not providing a comprehensive view of quasar abundance beyond the cosmic dawn. We present the predicted results of the Roman/Rubin high-redshift quasar survey,

Constraining the Evolution of the Ionizing Background and the Epoch of Reionization with z ∼ 6 Quasars. II. A Sample of 19 Quasars [PDF]

, 2005
We study the evolution of the ionization state of the intergalactic medium (IGM) at the end of the reionization epoch using moderate-resolution spectra of a sample of 19 quasars at 5.74 < zem < 6.42 discovered in the Sloan Digital Sky Survey.

Cosmic Bell Test Using Random Measurement Settings from High-Redshift Quasars. [PDF]

Physical Review Letters, 2018
In this Letter, we present a cosmic Bell experiment with polarization-entangled photons, in which measurement settings were determined based on real-time measurements of the wavelength of photons from high-redshift quasars, whose light was emitted ...

Automated quasar detection [PDF]

Monthly Notices of the Royal Astronomical Society, 1983
The existing spectral searches for quasars have increased the number of quasars known very substantially but have not contributed proportionately to an understanding of the collective properties because of the selection effects. To fully exploit the spectral searches we have developed the technique of automated quasar detection (AQD) using objective ...

cDC1 Subtype‐Specific In Vivo Targeting of Liposomes

Advanced Science, Volume 13, Issue 19, 2 April 2026.
Dendritic cells, particularly the cDC1 subtype, offer a promising target for drug delivery via liposomes due to their pivotal role in immune regulation, allowing for amplified therapeutic responses. Herein, we show an integration of physicochemical characterization and cell experiments to achieve effective in vivo cDC1 targeting through anti‐CLEC9A ...

The Cosmic Ultraviolet Baryon Survey (CUBS). VIII. Group Environment of the Most Luminous Quasars at z ≈ 1

The Astrophysical Journal
We investigate the group-scale environment of 15 luminous quasars (luminosity L _3000 > 10 ^46 erg s ^−1 ) from the Cosmic Ultraviolet Baryon Survey (CUBS) at redshift z ≈ 1.

Rapidly star-forming galaxies adjacent to quasars at redshifts exceeding 6 [PDF]

Nature, 2017
The existence of massive (1011 solar masses) elliptical galaxies by redshift z ≈ 4 (refs 1, 2, 3; when the Universe was 1.5 billion years old) necessitates the presence of galaxies with star-formation rates exceeding 100 solar masses per year at z > 6 ...
