Epstein‐Barr Virus Expressed Long Non‐Coding RNA (lncBARTs) Regulate EBV Latent Genome Replication

Advanced Science, EarlyView.
EBV produces abundant level of lncBARTs, which are essential for maintaining viral genome replication in EBV‐associated cancers. LncBARTs interact with a complex comprising BRD4, CTCF and viral protein EBNA1 at EBV oriP region. This interaction tethers oriP to host chromosomes, facilitating EBV episome replication.

Subaru High-z Exploration of Low-luminosity Quasars (SHELLQs). XXI. Candidate Red Quasars at z ≥ 6 from Near-infrared Photometry

The Astrophysical Journal
We present an analysis of near-infrared photometry of 59 quasars at 5.83  −24 mag) of the sample. This luminosity trend may support the idea that red quasars represent an evolutionary stage preceding unobscured quasars, often invoked in the merger-driven

New Superluminal Quasars [PDF]

Symposium - International Astronomical Union, 1986
Since 1977 we have been engaged on a project to survey the milliarcsecond structure and internal motions of a complete, unbiased sample of 65 radio sources (Pearson and Readhead 1984). One of the goals of the project was to discover more superluminal sources and find out how common they are.

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 ...

cDC1 Subtype‐Specific In Vivo Targeting of Liposomes

Advanced Science, EarlyView.
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 ...

X-ray Insights into the Nature of Quasars with Redshifted Broad Absorption Lines

, 2017
We present $Chandra$ observations of seven broad absorption line (BAL) quasars at $z=0.863$-2.516 with redshifted BAL troughs (RSBALs). Five of our seven targets were detected by $Chandra$ in 4-13 ks exposures with ACIS-S. The $\alpha_{\rm ox}$ values, $\

Understanding extreme quasar optical variability with CRTS – II. Changing-state quasars [PDF]

Monthly notices of the Royal Astronomical Society, 2019
We present the results of a systematic search for quasars in the Catalina Real-time Transient Survey exhibiting both strong photometric variability and spectroscopic variability over a decadal baseline. We identify 111 sources with specific patterns of

Overcoming PEG Antigenicity: Statistical PEG Isomers Reduce Antibody Binding

Advanced Science, EarlyView.
Conventional poly(ethylene glycol) (PEG) is commonly applied in biomedicine, but is now known to induce antibody formation. Here, it is shown that the development of “randomized PEG” (rPEG) featuring glycidyl methyl ether (GME) comonomers decreased antibody binding.

Red Type-1 Quasars after Cosmic Noon and Impact on L UV-related Quasar Statistics

The Astrophysical Journal
Over the past decades, nearly a million quasars have been explored to shed light on the evolution of supermassive black holes and galaxies. The ultraviolet-to-optical spectra of type-1 quasars particularly offer insights into their black hole activities.

Dust-Deficient Palomar-Green Quasars and the Diversity of AGN Intrinsic IR Emission

, 2017
To elucidate the intrinsic broadband infrared (IR) emission properties of active galactic nuclei (AGNs), we analyze the spectral energy distributions (SEDs) of 87 ...
