HST Proper Motion of Andromeda III. Another Satellite Coorbiting the M31 Satellite Plane

open access: yesThe Astrophysical Journal
We measure the absolute proper motion of Andromeda III (And III) using Advanced Camera for Surveys/Wide Field Channel and WFPC2 exposures spanning an unprecedented 22 yr time baseline.

Buzzard to Cardinal: Improved Mock Catalogs for Large Galaxy Surveys

open access: yesThe Astrophysical Journal
We present the Cardinal mock galaxy catalogs, a new version of the Buzzard simulation that has been updated to support ongoing and future cosmological surveys, including the Dark Energy Survey (DES), DESI, and LSST.

Learning by helping: Evidence from Chinese brokerages' community CSR

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary We propose that firms engaging in community corporate social responsibility (CSR) can acquire valuable local knowledge that improves their core operations. We test our proposition leveraging a unique context‐the Securities Association of China's pairing assistance scheme under the country's targeted poverty alleviation program.

Galaxy mergers in a fractal cosmology

open access: yesEuropean Physical Journal C: Particles and Fields
This work discusses the influence of galaxy mergers in the evolution of a parabolic Lemaître–Tolman–Bondi (LTB) cosmology with simultaneous big bang endowed with two consecutive single fractal galaxy distributions systems possessing fractal dimension D ...

The Extremely Low Mechanical Force Generated by Nano‐Pulling Induces Global Changes in the Microtubule Network, Nuclear Morphology, and Chromatin Transcription in Neurons

open access: yesSmall, EarlyView.
Nano‐pulling induces stabilization, reorganization, and reorientation of the microtubule network. The nucleus of stretched cells experiences increased lateral tension, becomes more spherical, and develops surface grooves. At the level of gene expression regulation, changes in nuclear morphology induce global chromatin remodeling, leading to reduced ...

Stacking and Analyzing MOSDEF Galaxies by Spectral Types: Implications for Dust Geometry and Galaxy Evolution

open access: yesThe Astrophysical Journal
We examine star formation and dust properties for a sample of 660 galaxies at 1.37 ≤ z ≤ 2.61 in the MOSDEF survey by dividing them into groups with similarly shaped spectral energy distributions (SEDs).

Science Triggers and Situational Interest in Everyday Family Life

open access: yesJournal of Research in Science Teaching, EarlyView.
ABSTRACT Interest in science is critical for science learning. The family plays a major role in supporting the development of children's interest in science by eliciting and fostering interest and engagement with science content and practice. This study characterizes triggers for interest in science in everyday family life and measures the duration of ...

Improving the Determination of Supernova Cosmological Redshifts by Using Galaxy Groups

open access: yesThe Astrophysical Journal
At the low-redshift end ( z < 0.05) of the Hubble diagram with Type Ia Supernovae (SNe Ia), the contribution to Hubble residual scatter from peculiar velocities (PVs) is of similar size to that due to the limitations of the standardization of the SN Ia ...
