Galaxy and Mass Assembly (GAMA): Low-redshift Quasars and Inactive Galaxies Have Similar Neighbors

The Astrophysical Journal, 2023
We explore the properties of galaxies in the proximity (within a ∼2 Mpc radius sphere) of Type I quasars at 0.1 < z

Deep spectroscopy of a young radio source at z=0.521

, 2005
9C J1503+4528 is a very young CSS radio galaxy, with an age of order 10^4 years. This source is an ideal laboratory for the study of the intrinsic host galaxy/IGM properties, radio source interactions, evidence for young stellar populations and the radio

Global environmental effects versus galaxy interactions [PDF]

, 2009
We explore properties of close galaxy pairs and merging systems selected from the Sloan Digital Sky Survey Data Release 4 in different environments with the aim to assess the relative importance of the role of interactions over global environmental ...

Artificial Intelligences: A Bridge Toward Diverse Intelligence and Humanity's Future

Advanced Intelligent Systems, EarlyView.
Many discussions of artificial intelligence fail to address deeper questions being raised by advances in developmental biology, neuroscience, bioengineering, and philosophy of mind. Novel beings, including technologically and biologically augmented humans, engineered life forms, hybrots, and others, require tools of the emerging field of diverse ...

The Growth of Galaxy Stellar Haloes over 0.2 ≤ z ≤ 1.1

The Astrophysical Journal
Galaxies are predicted to assemble their stellar haloes through the accretion of stellar material from interactions with their cosmic environment. Observations that trace stellar halo buildup probe the processes that drive galaxy size and stellar mass ...

HISTORY OF GALAXY INTERACTIONS AND THEIR IMPACT ON STAR FORMATION OVER THE LAST 7 Gyr FROM GEMS [PDF]

, 2009
We perform a comprehensive estimate of the frequency of galaxy mergers and their impact on star formation over z∼ 0.24–0.80 (lookback time Tb∼ 3–7 Gyr) using ∼3600 (M⩾ 1 × 109 M☉) galaxies with GEMS Hubble Space Telescope, COMBO-17, and Spitzer data. Our

Usage of the term provenance in LIS literature: An Annual Review of Information Science and Technology (ARIST) paper

Journal of the Association for Information Science and Technology, EarlyView.
Abstract Provenance is the story of how something has come to be. In this paper, we provide a systematic literature review to categorize the various notions of provenance in Information Sciences. The goal of this review is to paint a broader picture of the multiple uses of provenance at play and to enhance our understanding of the importance of ...

SDSS-IV MaNGA: Spatial Evolution of Gas-phase Metallicity Changes Induced by Galaxy Interactions

The Astrophysical Journal
Gas-phase metallicity in interacting and merging galaxies offers key insights into their star formation processes and evolutionary histories. This study investigates the spatial evolution of gas-phase metallicity (i.e., oxygen abundance, 12 + log(O/H ...

Leading Regenerative Transformation: Cognitive Frame Characteristics Shaping Leaders' Approaches to Organizational Development

Business Strategy and the Environment, EarlyView.
ABSTRACT As the urgency to address global crises such as climate change and inequality intensifies, the concept of regenerative development has emerged as a transformative approach going beyond sustainability to actively restore and enhance both ecological and social systems.

A Physically Motivated Framework to Compare the Merger Timescales of Isolated Low- and High-mass Galaxy Pairs Across Cosmic Time

The Astrophysical Journal
The merger timescales of isolated low-mass pairs (10 ^8 < M _* < 5 × 10 ^9 M _⊙ ) on cosmologically motivated orbits have not yet been studied in detail, though isolated high-mass pairs (5 × 10 ^9 < M _* < 10 ^11 M _⊙ ) have been studied extensively.
