Journal Article
Kim, H., Wyithe, J., Raskutti, S., Lacey, C., & Helly, J. (2013). The structure of reionization in hierarchical galaxy formation models. Monthly Notices of the Royal Astronomical Society, 428(3), 2467-2479. https://doi.org/10.1093/mnras/sts206

Understanding the epoch of reionization and the properties of the first galaxies represents an important goal for modern cosmology. The structure of reionization and hence the observed power spectrum of redshifted 21-cm fluctuations are known to be s...

GOODS-Herschel: radio-excess signature of hidden AGN activity in distant star-forming galaxies (2013)
Journal Article
Del Moro, A., Alexander, D., Mullaney, J., Daddi, E., Pannella, M., Bauer, F., …Xue, Y. (2013). GOODS-Herschel: radio-excess signature of hidden AGN activity in distant star-forming galaxies. Astronomy & Astrophysics, 549, Article A59. https://doi.org/10.1051/0004-6361/201219880

Context. A tight correlation exists between far-infrared and radio emission for star-forming galaxies (SFGs), which seems to hold out to high redshifts (z ≈ 2). Any excess of radio emission over that expected from star formation processes is most lik...

We present a panoramic narrow-band study of Hα emitters in the field of the z = 2.16 proto-cluster around PKS 1138−262 using MOIRCS on the Subaru Telescope. We find 83 Hα emitters down to a star formation rate of SFR (Hα) ∼ 10 M⊙ yr−1 across a ∼ 7 ×...

The formation of fossil oil within clay minerals i.e., mineral-catalyzed decarboxylation, is a mechanism awaiting a thorough chemical explanation. To contribute to such an explanation, the study presented here investigates this mechanism at the level... Read More about DFT+U investigation of the catalytic properties of ferruginous clay.

Satellites and haloes of dwarf galaxies (2013)
Journal Article

We study the abundance of satellite galaxies as a function of primary stellar mass using the Sloan Digital Sky Survey/Data Release 7 (SDSS/DR7) spectroscopic catalogue. In contrast with previous studies, which focused mainly on bright primaries, our... Read More about Satellites and haloes of dwarf galaxies.

Dust-obscured star formation in the outskirts of XMMU J2235.3-2557, a massive galaxy cluster at z = 1.4 (2013)

Dust-obscured star formation in the outskirts of XMMU J2235.3-2557, a massive galaxy cluster at z = 1.4. Monthly Notices of the Royal Astronomical Society, 433(2), 1287-1299. https://doi.org/10.1093/mnras/stt811

Star formation (SF) in the galaxy populations of local massive clusters is reduced with respect to field galaxies, and tends to be suppressed in the core region. Indications of a reversal of the SF–density relation have been observed in a few z > 1.4...

What did we learn in theory from the Delta ACP Saga? (2013)
Presentation / Conference Contribution
Lenz, A., Gersabeck, M., & Parkes, C. (2023, August). What did we learn in theory from the Delta ACP Saga?. Presented at CHARM 2013, Manchester UK

The measurement of CP violation in the charm sector triggered a lot of theoretical activities and re-considerations. Nevertheless currently neither theory nor experiment have reached definite conclusions about the origin of a large CP violating effec...
