Current Challenges of Transcription Compartmentalization Research

open access: yesAdvanced Science, EarlyView.
Transcription factors, coactivators, and RNA polymerase II assemble into transcription compartments ranging from small, defined complexes to liquid‐like condensates. This review unifies these seemingly competing descriptions along a single continuum and asks what these compartments have been shown to do, and what they have not, revealing that the most ...

OGLE-2016-BLG-1195Lb: A Sub-Neptune Beyond the Snow Line of an M-dwarf Confirmed by Keck Adaptive Optics

open access: yesThe Astronomical Journal
We present the analysis of high-resolution follow-up observations of OGLE-2016-BLG-1195 using Laser Guide Star Adaptive Optics with Keck, seven years after the event’s peak.

DEEP OPTICAL PHOTOMETRY OF SIX FIELDS IN THE ANDROMEDA GALAXY [PDF]

open access: yesThe Astrophysical Journal Supplement Series, 2009
Using the Advanced Camera for Surveys on the Hubble Space Telescope, we have obtained deep optical images reaching well below the oldest main sequence turnoff in six fields of the Andromeda Galaxy. The fields fall at four positions on the southeast minor axis, one position in the giant stellar stream, and one position on the northeast major axis. These

Targeting the KCNC3‐Dependent Anterior Insular‐Lateral Orbitofrontal Cortex Glutamatergic Circuit Attenuates Post‐Traumatic Anxiety

open access: yesAdvanced Science, EarlyView.
Frontal lobe traumatic brain injury is associated with hyperactivity of an insular–orbitofrontal circuit in both patients and mice. By combination of integrating functional imaging, cell‐type–specific circuit manipulation, single‐cell transcriptomics, and whole‐cell recordings, this work identifies the downregulation of the potassium channel KCNC3 in ...

Optical Photometry of Black-Hole Candidates [PDF]

open access: yesSymposium - International Astronomical Union, 1996
The orbital light curves of SXTs are discussed. In principle, the orbital inclination can be determined from the ellipsoidal variations, allowing a complete solution for the component masses. Complications in this analysis are described, and the evidence for superhumps in the light curves is reviewed.

The THESEUS Space Mission and the Infrared Telescope Calibration Unit

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT The Transient High‐Energy Sky and Early Universe Surveyor (THESEUS) is an ESA M7 mission concept currently in Phase A, designed to exploit gamma‐ray bursts to probe the early Universe while advancing multi‐messenger and time‐domain astrophysics. To achieve its ambitious goals, THESEUS will combine wide‐band x‐ray and gamma‐ray monitors with an

Optical and infrared photometry of Arakelian 120 [PDF]

open access: yesPublications of the Astronomical Society of the Pacific, 1978
Optical and IR photometry of the Seyfert class 1 galaxy Arakelian 120 covering the wavelength range from 0.36 to 3.5 microns is reported. The observed fluxes are found to consist of contributions of starlight from the surrounding galaxy, emission lines, thermal gas continuum, nonthermal radiation, and possible IR emission from dust.

Feasibility Study for Application of Digitized Henize Mt. Wilson Michigan Southern Sky Hα$$ \boldsymbol{\alpha} $$ Survey Low‐Dispersive Spectral Plates for Searches for Anomalous and Highly Redshifted Objects

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT The goal of this study is to confirm the feasibility of the use of digitized low dispersive MtWilson Michigan Southern Sky Hα$$ \alpha $$ survey astronomical photographic plates for modern astrophysical research. The detection of highly redshifted objects, such as early galaxies and quasars, is fundamental to understanding the universe's ...
