We summarize the results obtained from the MUNICS K-band selected Galaxy survey thus far. MUNICS is a wide-area, medium-deep, photometric and spectroscopic survey selected in the K band, targeting randomly-selected high Galactic latitude fields. It covers an area of roughly one square degree in the K and J bands with optical imaging in the I, R, V, and B bands in 0.5 square degrees. The MUNICS photometric survey is complemented by spectroscopic follow-up observations down to limits of K<17.5 (wide area) and K<19.5 (smaller area). We have obtained 593 redshifts to this date. Here, we present results concerning the evolution of the K-band luminosity function to z ~ 1, both from the full photometric redshift sample and from the spectroscopic sample alone. We also report on new results concerning the evolution of the stellar mass function to z ~ 1. We fit stellar population synthesis models to our multicolor photometry to obtain M/L values for each source. We detect significant evolution in the stellar mass function and we find that more massive systems evolve faster in number density than less massive systems. We also measure the evolution of the total stellar mass density of the universe and find that about half the present day stellar mass formed since z ~ 1.

One key problem in astrophysics is understanding how and why galaxies switch off their star formation, building the quiescent population that we observe in the local Universe. From the GAMA and VIPERS surveys, we use spectroscopic indices to select q
uiescent and candidate transition galaxies. We identify potentially rapidly transitioning post-starburst galaxies, and slower transitioning green-valley galaxies. Over the last 8 Gyrs the quiescent population has grown more slowly in number density at high masses (M$_*>10^{11}$M$_odot$) than at intermediate masses (M$_*>10^{10.6}$M$_odot$). There is evolution in both the post-starburst and green valley stellar mass functions, consistent with higher mass galaxies quenching at earlier cosmic times. At intermediate masses (M$_*>10^{10.6}$M$_odot$) we find a green valley transition timescale of 2.6 Gyr. Alternatively, at $zsim0.7$ the entire growth rate could be explained by fast-quenching post-starburst galaxies, with a visibility timescale of 0.5 Gyr. At lower redshift, the number density of post-starbursts is so low that an unphysically short visibility window would be required for them to contribute significantly to the quiescent population growth. The importance of the fast-quenching route may rapidly diminish at $z<1$. However, at high masses (M$_*>10^{11}$M$_odot$), there is tension between the large number of candidate transition galaxies compared to the slow growth of the quiescent population. This could be resolved if not all high mass post-starburst and green-valley galaxies are transitioning from star-forming to quiescent, for example if they rejuvenate out of the quiescent population following the accretion of gas and triggering of star formation, or if they fail to completely quench their star formation.
We present X-ray and spectroscopic confirmation of a cluster assembling from multiple, distinct galaxy groups at z=0.371. Initially detected in the Las Campanas Distant Cluster Survey, the structure contains at least four X-ray detected groups that l
ie within a maximum projected separation of 4 Mpc and within dv=550 km/s of one another. Using Chandra imaging and wide-field optical spectroscopy, we show that the individual groups lie on the local sigma-T relation, and derive a total mass of M>=5e14 solar masses for the entire structure. We demonstrate that the groups are gravitationally bound to one another and will merge into a single cluster with >=1/3 the mass of Coma. We also find that although the cluster is in the process of forming, the individual groups already have a higher fraction of passive members than the field. This result indicates that galaxy evolution on group scales is key to developing the early-type galaxies that dominate the cluster population by z~0.
The MUNICS project is an ongoing imaging survey designed to cover 3 sq. degrees in V,R,I,J,K. We describe here partial results of the project concerning the clustering properties of K < 19.5 galaxies in scales of 3.6 to 63.0 over an area of $sim 800
arcmin^2$. We present K data for a sample of 20 fields, five of which contain $z > 0.5$ radio-loud quasars with steep spectra, eight contain $z > 0.5$ radio-loud quasars with flat spectra and seven are high-galactic latitude fields with no quasars in them. The two-point angular correlation function for the total sample shows significant clustering at $sim 5 sigma$ level of K=19.5 galaxies. The correlation angle of the galaxies is $theta_0 = 1.7 pm 0.4$ for K < 19 mag and $theta_0 = 1.0 pm 0.2$ for K < 19.5 mag. When the correlation functions for the subsamples are considered, the mean $omega(theta)$ amplitude of the fields which contain steep-spectra $z > 0.5$ radio-loud quasars is determined to be $sim 2.0 - 2.5$ that of the high-galactic latitude fields.
We study the stellar mass assembly of the Spiderweb Galaxy (MRC 1138-262), a massive z = 2.2 radio galaxy in a protocluster and the probable progenitor of a brightest cluster galaxy. Nearby protocluster galaxies are identified and their properties ar
e determined by fitting stellar population models to their rest-frame ultraviolet to optical spectral energy distributions. We find that within 150 kpc of the radio galaxy the stellar mass is centrally concentrated in the radio galaxy, yet most of the dust-uncorrected, instantaneous star formation occurs in the surrounding low-mass satellite galaxies. We predict that most of the galaxies within 150 kpc of the radio galaxy will merge with the central radio galaxy by z = 0, increasing its stellar mass by up to a factor of ~ 2. However, it will take several hundred Myr for the first mergers to occur, by which time the large star formation rates are likely to have exhausted the gas reservoirs in the satellite galaxies. The tidal radii of the satellite galaxies are small, suggesting that stars and gas are being stripped and deposited at distances of tens of kpc from the central radio galaxy. These stripped stars may become intracluster stars or form an extended stellar halo around the radio galaxy, such as those observed around cD galaxies in cluster cores.
We present a method to flexibly and self-consistently determine individual galaxies star formation rates (SFRs) from their host haloes potential well depths, assembly histories, and redshifts. The method is constrained by galaxies observed stellar ma
ss functions, SFRs (specific and cosmic), quenched fractions, UV luminosity functions, UV-SM relations, IRX-UV relations, auto- and cross-correlation functions (including quenched and star-forming subsamples), and quenching dependence on environment; each observable is reproduced over the full redshift range available, up to 0<z<10. Key findings include: galaxy assembly correlates strongly with halo assembly; quenching at z>1 correlates strongly with halo mass; quenched fractions at fixed halo mass decrease with increasing redshift; massive quenched galaxies reside in higher-mass haloes than star-forming galaxies at fixed galaxy mass; star-forming and quenched galaxies star formation histories at fixed mass differ most at z<0.5; satellites have large scatter in quenching timescales after infall, and have modestly higher quenched fractions than central galaxies; Planck cosmologies result in up to 0.3 dex lower stellar mass-halo mass ratios at early times; and, nonetheless, stellar mass-halo mass ratios rise at z>5. Also presented are revised stellar mass-halo mass relations for all, quenched, star-forming, central, and satellite galaxies; the dependence of star formation histories on halo mass, stellar mass, and galaxy SSFR; quenched fractions and quenching timescale distributions for satellites; and predictions for higher-redshift galaxy correlation functions and weak lensing surface densities. The public data release (DR1) includes the massively parallel (>10^5 cores) implementation (the UniverseMachine), the newly compiled and remeasured observational data, derived galaxy formation constraints, and mock catalogues including lightcones.
