Journal Article
Wang, L., Norberg, P., Brough, S., Brown, M., da Cunha, E., Davies, L., Driver, S., Holwerda, B., Hopkins, A., Lara-Lopez, M., Liske, J., Loveday, J., Grootes, M., Popescu, C., & Wright, A. (2018). Galaxy and Mass Assembly (GAMA): The environmental dependence of the galaxy main sequence. Astronomy & Astrophysics, 618, Article A1. https://doi.org/10.1051/0004-6361/201832697

Aims: We aim to investigate if the environment (characterised by the host dark matter halo mass) plays any role in shaping the galaxy star formation main sequence (MS). Methods: The Galaxy and Mass Assembly project (GAMA) combines a spectroscopic sur... Read More about Galaxy and Mass Assembly (GAMA): The environmental dependence of the galaxy main sequence.

The PAU Survey: spectral features and galaxy clustering using simulated narrow-band photometry (2018)
Journal Article
Stothert, L., Norberg, P., Baugh, C., Alarcon, A., Amara, A., Carretero, J., Castander, F., Eriksen, M., Fernandez, E., Fosalba, P., Garcia-Bellido, J., Gaztanaga, E., Hoekstra, H., Padilla, C., Refregier, A., Sanchez, E., & Tortorelli, L. (2018). The PAU Survey: spectral features and galaxy clustering using simulated narrow-band photometry. Monthly Notices of the Royal Astronomical Society, 481(3), 4221-4235. https://doi.org/10.1093/mnras/sty2491

We present a mock catalogue for the Physics of the Accelerating Universe Survey (PAUS) and use it to quantify the competitiveness of narrow-band imaging for measuring spectral features and galaxy clustering. The mock agrees with observed number count... Read More about The PAU Survey: spectral features and galaxy clustering using simulated narrow-band photometry.

The impact of assembly bias on the halo occupation in hydrodynamical simulations (2018)
Journal Article
Artale, M., Zehavi, I., Contreras, S., & Norberg, P. (2018). The impact of assembly bias on the halo occupation in hydrodynamical simulations. Monthly Notices of the Royal Astronomical Society, 480(3), 3978-3992. https://doi.org/10.1093/mnras/sty2110

We investigate the variations in galaxy occupancy of the dark matter haloes with the large-scale environment and halo formation time, using two state-of-the-art hydrodynamical cosmological simulations, EAGLE and Illustris. For both simulations, we us... Read More about The impact of assembly bias on the halo occupation in hydrodynamical simulations.

Multiwavelength scaling relations in galaxy groups: a detailed comparison of GAMA and KiDS observations to BAHAMAS simulations (2018)
Journal Article
Jakobs, A., Viola, M., McCarthy, I., van Waerbeke, L., Hoekstra, H., Robotham, A., Hinshaw, G., Hojjati, A., Tanimura, H., Tröster, T., Baldry, I., Heymans, C., Hildebrandt, H., Kuijken, K., Norberg, P., Schaye, J., Sifón, C., van Uitert, E., Valentijn, E., Verdoes Kleijn, G., & Wang, L.

Monthly Notices of the Royal Astronomical Society, 480(3), 3338-3355. https://doi.org/10.1093/mnras/sty2017

We study the scaling relations between the baryonic content and total mass of groups of galaxies, as these systems provide a unique way to examine the role of non-gravitational processes in structure formation. Using Planck and ROSAT data, we conduct... Read More about Multiwavelength scaling relations in galaxy groups: a detailed comparison of GAMA and KiDS observations to BAHAMAS simulations.

Galaxy And Mass Assembly (GAMA): the signatures of galaxy interactions as viewed from small scale galaxy clustering (2018)
Journal Article
Gunawardhana, M., Norberg, P., Zehavi, I., Farrow, D., Loveday, J., Hopkins, A., Davies, L., Wang, L., Alpaslan, M., Bland-Hawthorn, J., Brough, S., Holwerda, B., Owers, M., & Wright, A. (2018). Galaxy And Mass Assembly (GAMA): the signatures of galaxy interactions as viewed from small scale galaxy clustering. Monthly Notices of the Royal Astronomical Society, 479(2), 1433-1464. https://doi.org/10.1093/mnras/sty1638

Statistical studies of galaxy–galaxy interactions often utilize net change in physical properties of progenitors as a function of the separation between their nuclei to trace both the strength and the observable time-scale of their interaction. In th... Read More about Galaxy And Mass Assembly (GAMA): the signatures of galaxy interactions as viewed from small scale galaxy clustering.

Galaxy Tagging: photometric redshift refinement and group richness enhancement (2018)
Journal Article
Kafle, P., Robotham, A., Driver, S., Deeley, S., Norberg, P., Drinkwater, M., & Davies, L. (2018). Galaxy Tagging: photometric redshift refinement and group richness enhancement. Monthly Notices of the Royal Astronomical Society, 479(3), 3746-3758. https://doi.org/10.1093/mnras/sty1536

We present a new scheme, galtag, for refining the photometric redshift measurements of faint galaxies by probabilistically tagging them to observed galaxy groups constructed from a brighter, magnitude-limited spectroscopy survey. First, this method i... Read More about Galaxy Tagging: photometric redshift refinement and group richness enhancement.

The Impact of Assembly Bias on the Galaxy Content of Dark Matter Halos (2018)
Journal Article

We study the dependence of the galaxy content of dark matter halos on large-scale environment and halo formation time using semi-analytic galaxy models applied to the Millennium simulation. We analyze subsamples of halos at the extremes of these dist... Read More about The Impact of Assembly Bias on the Galaxy Content of Dark Matter Halos.
