Cosmic CARNage I: on the calibration of galaxy formation models
Alexander Knebe, Frazer R. Pearce, Violeta Gonzalez-Perez +31
We present a comparison of nine galaxy formation models, eight semi-analytical and one halo occupation distribution model, run on the same underlying cold dark matter simulation (c…
Abundance ratios in dwarf elliptical galaxies
Ş. Şen, R. F. Peletier, A. Boselli +14
We determine abundance ratios of 37 dwarf ellipticals (dEs) in the nearby Virgo cluster. This sample is representative of the early-type population of galaxies in the absolute magn…
Arp 202: a TDG formed in a parent's extended dark matter halo?
T. C. Scott, P. Lagos, S. Ramya +6
We report on H + [NII] imaging of the Arp 202 interacting pair and its tidal dwarf galaxy (TDG) candidate as well as a GMOS long slit spectrum from the TDG candidate, observed w…
Environmental Dependence of Type Ia Supernova Luminosities from a Sample without a Local-Global Difference in Host Star Formation
Young-Lo Kim, Mathew Smith, Mark Sullivan +1
It is now established that there is a dependence of the luminosity of type Ia supernovae (SNe Ia) on environment: SNe Ia in young, star-forming, metal-poor stellar populations appe…
Deep VLA observations of the cluster 1RXS J0603.3+4214 in the frequency range 1-2 GHz
K. Rajpurohit, M. Hoeft, R. J. van Weeren +11
We report L-band VLA observations of 1RXS J0603.3+4214, a cluster that hosts a bright radio relic, known as the Toothbrush, and an elongated giant radio halo. These new observation…
Constraints on the Evolution of the Galaxy Stellar Mass Function II: Quenching Timescale of Galaxies and its Implication for their Star Formation Rate
E. Contini, X. Kang, A. D. Romeo +2
We study the connection between the observed star formation rate-stellar mass (SFR-) relation and the evolution of the stellar mass function (SMF) by means of a subhalo abunda…
UGC 4703 interacting pair near to an isolated spiral galaxy NGC 2718: A Milky Way Magellanic Cloud analogue
Sanjaya Paudel, C. Sengupta
We present an analysis of physical and morphological properties of an interacting pair of dwarf galaxies UGC 4703 located at the vicinity of an isolated Milky-Way (MW) type spiral…
Ionized Gas Kinematics along the Large-Scale Radio Jets in Type 2 AGNs
Huynh Anh N. Le, Jong-Hak Woo, Donghoon Son +4
To investigate the connection between radio activity and AGN outflows, we present a study of ionized gas kinematics based on [O III] 5007 emission line along the large-scale rad…
Gas flows in the circumgalactic medium around simulated high-redshift galaxies
Peter Mitchell, Jeremy Blaizot, Julien Devriendt +4
We analyse the properties of circumgalactic gas around simulated galaxies in the redshift range z >= 3, utilising a new sample of cosmological zoom simulations. These simulations a…
Ionized gas outflows in infrared-bright dust-obscured galaxies selected with WISE and SDSS
Yoshiki Toba, Hyun-Jin Bae, Tohru Nagao +5
We present the ionized gas properties of infrared (IR)-bright dust-obscured galaxies (DOGs) that show an extreme optical/IR color, , selected with the Sl…
Cosmological evolution of the Nitrogen abundance
Elisabeth Vangioni, Irina Dvorkin, Keith A. Olive +5
The abundance of nitrogen in the interstellar medium is a powerful probe of star for- mation processes over cosmological timescales. Since nitrogen can be produced both in massive…
Medium-resolution Spectroscopy of Red Giant Branch Stars in Centauri
Deokkeun An, Young Sun Lee, Jae In Jung +5
We present [Fe/H] and [Ca/Fe] of red giant branch (RGB) members of the globular cluster Centauri. We collect medium-resolution () spectra using the Blanco…
On the Structure of the AGN Torus through the Fraction of Optically-Selected Type 1 AGNs
Honggeun Khim, Sukyoung K. Yi
The ratio in number between unobscured (type 1) and obscured (type 2) AGNs is often used to explore the structure of the torus in the unified scheme for active galactic nuclei (AGN…
The SAMI Galaxy Survey: Global stellar populations on the size-mass plane
Nicholas Scott, S. Brough, Scott M. Croom +20
We present an analysis of the global stellar populations of galaxies in the SAMI Galaxy Survey. Our sample consists of 1319 galaxies spanning four orders of magnitude in stellar ma…
New insights on the origin of multiple stellar populations in globular clusters
Jaeyeon Kim, Young-Wook Lee
In order to investigate the origin of multiple stellar populations in the halo and bulge of the Milky Way, we have constructed chemical evolution models for the low-mass proto-Gala…
Star Formation of Merging Disk Galaxies with AGN Feedback Effects
Jongwon Park, Rory Smith, Sukyoung K. Yi
Using numerical hydrodynamics code, we perform various idealized galaxy merger simulations to study the star formation (SF) of two merging disk galaxies. Our simulations include ga…
Young, metal-enriched cores in early-type dwarf galaxies in the Virgo cluster based on colour gradients
Linda Urich, Thorsten Lisker, Joachim Janz +11
Early-type dwarf galaxies are not simply featureless, old objects, but were found to be much more diverse, hosting substructures and a variety of stellar population properties. To…
