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

Hidden No More: Spotlight on Tidal Disruption Events in Active Galactic Nuclei
Astronomische Nachrichten, EarlyView.ABSTRACT Tidal disruption events (TDEs) are typically discovered in previously quiescent galaxies. However, earlier studies have revealed a handful of TDEs occurring in pre‐existing active galactic nuclei (AGN). We discuss AT2019aalc, a promising TDE candidate in an AGN, and compare it to similar sources.

Cold Gas Infall onto a Brightest Group Galaxy via a Gas-rich Minor Merger
The Astrophysical Journal LettersDust and cold gas are not uncommon in nearby early-type galaxies (ETGs) and represent an important aspect of their evolution. However, their origin has been debated for decades.

The relation between bar formation, galaxy luminosity, and environment
, 2013 We derive the bar fraction in three different environments ranging from the field to Virgo and Coma clusters, covering an unprecedentedly large range of galaxy luminosities (or, equivalently, stellar masses).

Form flows function: Learner‐centered game Re‐design in a STEM classroom
British Educational Research Journal, EarlyView.Abstract Re‐designing games facilitates interest‐driven learning and immerses learners in systems thinking. However, there are limited studies exploring how the form and function of tabletop games influence learners' design decisions and learning experiences. To address this gap, we conducted a mixed‐methods study in a STEM classroom in western Canada.

Anatomy of the Star Formation in a Tidally Disturbed Disk Galaxy: NGC 3718
The Astrophysical JournalWe present a UV, optical, and near-IR study of the star-forming complexes in the nearby peculiar galaxy NGC 3718, using Ultraviolet Imaging telescope, Galaxy Evolution Explorer, Spitzer, and DECam Legacy Survey imaging data.

The nature of obscuration in AGN: II. insights from clustering properties
, 2014 Based on large optical and mid-infrared (IR) surveys, we investigate the relation between nuclear activity in local Seyfert 2 galaxies and galaxy interactions using a statistical neighbour counting technique.

Chemie Ingenieur Technik, EarlyView.All energy matters Let us broaden the discussion on solutions to climate change. Greenhouse gases have upset the delicate equilibrium of the Earth's energy balance. Consequently, all sources of heat affect the temperature of the Earth. Although the amount of additional heat generated by humans is a fraction of that produced by the sun, it is generated ...

The Growth of Galaxy Stellar Haloes over 0.2 ≤ z ≤ 1.1
The Astrophysical JournalGalaxies 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 ...

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
