A complete catalogue of merger fractions in AGN hosts
Carolin Villforth
Sep 11, 2023
Despite the importance of Active Galactic Nuclei (AGN) in galaxy evolution, the mechanisms that fuel AGN activity remain poorly understood. Theoretical models suggest that major mergers of galaxies contribute strongly to AGN...
Stalagmite evidence of Last Glacial Maximum to early Holocene climate variability in southwestern Iran
Mojgan Soleimani, Alireza Nadimi, Gabriella Koltai, Yuri Dublyansky, Stacy Carolin, Christoph Spotl
Oct 29, 2022
Glacial periods and their terminations are useful for assessing the full scale of natural climate variability in the diverse climate regions of West Asia (i.e. deserts, mountains, alluvial plains, coastal zones). In this study...

The host galaxies and narrow-line regions of four double-peaked [OIII] AGNs
Major gas-rich mergers of galaxies are expected to play an important role in triggering and fueling luminous active galactic nuclei (AGNs). The mechanism of AGN fueling during mergers, however, remains poorly understood. We...
Slip-Rate on the Main Köpetdag (Kopeh Dagh) Strike-Slip Fault, Turkmenistan, and the Active Tectonics of the South Caspian
RT Walker, Y Bezmenov, G Begenjev, S Carolin, N Dodds, C Gruetzner, JA Jackson, R Mirzin, Z Mousavi, EJ Rhodes
Aug 11, 2021
Abstract: We provide the first measurement of strike‐slip and shortening rates across the 200‐km‐long right‐lateral strike‐slip Main Köpetdag Fault (MKDF) in Turkmenistan. Strike‐slip and shortening components are accommodated...
Evolution of tropical land temperature across the last glacial termination.
MH Løland, Y Krüger, A Fernandez, F Buckingham, SA Carolin, H Sodemann, JF Adkins, KM Cobb, AN Meckler
Oct 03, 2022
The tropical West Pacific hosts the warmest part of the surface ocean and has a considerable impact on the global climate system. Reconstructions of past temperature in this region can elucidate climate connections between the...

The redshift evolution of major merger triggering of luminous AGN
Timothy Hewlett, Carolin Villforth, Vivienne Wild, Jairo Mendez-Abreu, Milena Pawlik, Kate Rowlands
May 01, 2017
Active galactic nuclei (AGN), particularly the most luminous AGN, are commonly assumed to be triggered through major mergers, however observational evidence for this scenario is mixed. To investigate any influence of galaxy...
Artefactual nanoparticle activation of the inflammasome platform
AIM: To determine whether in vitro experimental conditions dictate cellular activation of the inflammasome by apatitic calcium phosphate nanoparticles. MATERIAL & METHODS: The responses of blood-derived primary human cells to in...
Phytophthora palmivora establishes tissue-specific intracellular infection structures in the earliest divergent land plant lineage.
The expansion of plants onto land was a formative event that brought forth profound changes to the earth's geochemistry and biota. Filamentous eukaryotic microbes developed the ability to colonize plant tissues early during the...

A simple non-parametric method for resolving merged doublet lines
Doublet line emission and absorption are common in astronomical sources (e.g. [OIII], [O II], NaD, MgII). In many cases, complex kinematics in the emitting source can cause the doublet lines to merge, making characterization...

Copy Number and Prevalence of Porcine Endogenous Retroviruses (PERVs) in German Wild Boars.
Luise Krüger, Milena Stillfried, Carolin Prinz, Vanessa Schröder, Lena Katharina Neubert, Joachim Denner
Apr 09, 2020
Porcine endogenous retroviruses (PERVs) are integrated in the genome of pigs and are transmitted like cellular genes from parents to the offspring. Whereas PERV-A and PERV-B are present in all pigs, PERV-C was found to be in...
Robotic reverberation mapping of the broad-line radio galaxy 3C 120
Michael Hlabathe, David Starkey, Keith Horne, Encarni Romero-Colmenero, Steven Crawford, Stefano Valenti, Hartmut Winkler, Aaron Barth, Christopher Onken, David Sand, Tommaso Treu, Aleksandar Diamond-Stanic, Carolin Villforth
Sep 30, 2020
We carried out photometric and spectroscopic observations of the well-studied broad-line radio galaxy 3C 120 with the Las Cumbres Observatory (LCO) global robotic telescope network from 2016 December to 2018 April as part of the...
Host galaxies of luminous z ∼ 0.6 quasars
Carolin Villforth, T Hamilton, M. M. Pawlik, T. Hewlett, K Rowlands, H. Herbst, F Shankar, A. Fontana, Fred Hamann, A. M. Koekemoer, J. Pforr, J. R. Trump, Stijn Wuyts
Apr 30, 2017
Galaxy interactions are thought to be one of the main triggers of active galactic nuclei (AGN), especially at high luminosities, where the accreted gas mass during the AGN lifetime is substantial. Evidence for a connection...

Feb 04, 2020
Bacterial resistance against antibiotics often involves multiple mechanisms that are interconnected to ensure robust protection. So far, the knowledge about underlying regulatory features of those resistance networks is sparse...

Reduction of T-Helper Cell Responses to Recall Antigen Mediated by Codelivery with Peptidoglycan via the Intestinal Nanomineral-Antigen Pathway.
Naturally occurring intestinal nanomineral particles constituently form in the mammalian gut and trap luminal protein and microbial components. These cargo loaded nanominerals are actively scavenged by M cells of intestinal...
