We present the HI-MaNGA programme of HI follow-up for Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey. MaNGA, which is part Fourth phase Sloan Digital Sky Surveys (SDSS-IV), in process obtaining integral field unit (IFU) spectroscopy a sample ~10,000 nearby galaxies. give an overview 21cm radio observing plans and progress data first 331 galaxies observed 2016 season Robert C. Bryd Green Bank Telescope (GBT). also provide cross match current MaNGA (DR15) with publicly...
We explored a suite of high-resolution cosmological simulations from the First Billion Years Project (FiBY) at $z \geq 6$. All substructures within have been identified with SUBFIND algorithm. From our analysis, two distinct groups objects emerge. hypothesise that in first group, which appear to high baryon fraction ($f_{\rm b} 0.95$), are possible infant GC candidates. Objects belonging second group stellar star} 0.95$) and show potential resemblance ultra-faint dwarf galaxies. The this...
Abstract Supermassive black holes (BHs) residing in brightest cluster galaxies (BCGs) are overly massive when considering the local relationships between BH mass and stellar bulge or velocity dispersion. Because of location these BHs within cluster, large-scale processes may aid growth BCGs. In this work, we study a sample 71 galaxy clusters to explore relationship mass, BCG, total gravitating host clusters. difficulties obtaining dynamically measured masses distant galaxies, use Fundamental...
Abstract Setting the formation of globular clusters (GCs) within a cosmological context and characterising properties proto-GCs at high redshift is currently major challenge. In this work, we address that challenge by exploring suit high-resolution simulations from First Billion Years (FiBY) project z ⩾6 to investigate theoretical scenarios concerning old, low-mass stellar systems with particular focus on GCs. Two distinct groups objects are identified in simulations. The first group...
We investigate the formation of infant globular cluster (GC) candidates in high-resolution cosmological simulations from First Billion Years (FiBY) project. By analysing evolution systems energy and angular momentum plane, we identify redshift at which GCs first became gravitationally bound, find evidence radial infall their gaseous stellar components. The collapse appears to be driven by internal self-gravity, however, initial trigger is sourced external environment. phase space behaviour...
