GOALS-JWST: Mid-Infrared Spectroscopy of the Nucleus of NGC 7469
L. Armus, T. Lai, V. U +32
We present mid-infrared spectroscopic observations of the nucleus of the nearby Seyfert galaxy NGC 7469 taken with the MIRI instrument on the James Webb Space Telescope (JWST) as p…
Self-Supervised Clustering on Image-Subtracted Data with Deep-Embedded Self-Organizing Map
Y. -L. Mong, K. Ackley, T. L. Killestein +45
Developing an effective automatic classifier to separate genuine sources from artifacts is essential for transient follow-ups in wide-field optical surveys. The identification of t…
Group quenching and galactic conformity at low redshift
M. Treyer, K. Kraljic, S. Arnouts +13
We quantify the quenching impact of the group environment using the spectroscopic survey Galaxy and Mass Assembly (GAMA) to z=0.2. The fraction of red (quiescent) galaxies, whether…
The XXL Survey: XXII. The XXL-North spectrophotometric sample and galaxy stellar mass function in X-ray detected groups and clusters
V. Guglielmo, B. M. Poggianti, B. Vulcani +42
The fraction of galaxies bound in groups in the nearby Universe is high (50% at z~0). Systematic studies of galaxy properties in groups are important in order to improve our unders…
Photometric redshifts for the Kilo-Degree Survey. Machine-learning analysis with artificial neural networks
M. Bilicki, H. Hoekstra, M. J. I. Brown +24
We present a machine-learning photometric redshift analysis of the Kilo-Degree Survey Data Release 3, using two neural-network based techniques: ANNz2 and MLPQNA. Despite limited c…
The stellar-to-halo mass relation of GAMA galaxies from 100 square degrees of KiDS weak lensing data
Edo van Uitert, Marcello Cacciato, Henk Hoekstra +26
We study the stellar-to-halo mass relation of central galaxies in the range 9.7<log_10(M_*/h^-2 M_sun)<11.7 and z<0.4, obtained from a combined analysis of the Kilo Degree Survey (…
Galaxy And Mass Assembly (GAMA): Spectroscopic analysis
A. M. Hopkins, S. P. Driver, S. Brough +79
The Galaxy And Mass Assembly (GAMA) survey is a multiwavelength photometric and spectroscopic survey, using the AAOmega spectrograph on the Anglo-Australian Telescope to obtain spe…
Galaxy And Mass Assembly (GAMA): Galaxy environments and star formation rate variations
D. B. Wijesinghe, A. M. Hopkins, S. Brough +23
We present a detailed investigation into the effects of galaxy environment on their star formation rates (SFR) using galaxies observed in the Galaxy and Mass Assembly Survey (GAMA)…
Galaxy and Mass Assembly (GAMA): ugriz galaxy luminosity functions
J. Loveday, P. Norberg, I. K. Baldry +31
Galaxy and Mass Assembly (GAMA) is a project to study galaxy formation and evolution, combining imaging data from ultraviolet to radio with spectroscopic data from the AAOmega spec…
AGES: The AGN and Galaxy Evolution Survey
C. S. Kochanek, D. J. Eisenstein, R. J. Cool +12
The AGN and Galaxy Evolution Survey (AGES) is a redshift survey covering, in its standard fields, 7.7 square degrees of the Bootes field of the NOAO Deep Wide-Field Survey (NDWFS).…
GRB 011121: A Massive Star Progenitor
P. A. Price, E. Berger, D. E. Reichart +29
Of the cosmological gamma-ray bursts, GRB 011121 has the lowest redshift, z=0.36. More importantly, the multi-color excess in the afterglow detected in the Hubble Space Telescope (…
