The Solar Orbiter Mission: an Energetic Particle Perspective

R. Gómez-Herrero, J. Rodríguez-Pacheco, R. F. Wimmer-Schweingruber +27

Solar Orbiter is a joint ESA-NASA mission planed for launch in October 2018. The science payload includes remote-sensing and in-situ instrumentation designed with the primary goal…

The Long Period of 3He-rich Solar Energetic Particles Measured by Solar Orbiter on 2020 November 17-23

R. Bucik, G. M. Mason, R. Gomez-Herrero +31

We report observations of a relatively long period of 3He-rich solar energetic particles (SEPs) measured by Solar Orbiter. The period consists of several well-resolved ion injectio…

GOYA Survey: U and B Number Counts in the Groth-Westphal Strip

M. C. Eliche-Moral, M. Balcells, M. Prieto +3

We present U and B galaxy differential number counts from a field of ~900 arcmin^2, based on GOYA Survey imaging of the HST Groth-Westphal strip. Source detection efficiency correc…

EMIR, the near-infrared camera and multi-object spectrograph for the GTC

F. Garzón, M. Balcells, J. Gallego +18

We present EMIR, a powerful near-infrared (NIR) camera and multi-object spectrograph (MOS) installed at the Nasmyth focus of the 10.4 m GTC. EMIR was commissioned in mid-2016 and i…

Robust determination of the major merger fraction at z = 0.6 in Groth Strip

C. López-Sanjuan, M. Balcells, C. E. García-Dabó +6

(Abridged) We measure the fraction of galaxies undergoing disk-disk major mergers (f_m) at intermediate redshifts (0.35 <= z < 0.85) by studying the asymmetry index A of galaxy ima…

Optical Surface Photometry of a Sample of Disk Galaxies. II Structural Components

M. Prieto, J. A. L. Aguerri, A. M. Varela +1

This work presents the structural decomposition of a sample of 11 disk galaxies, which span a range of different morphological types. The U, B, V, R, and I photometric information…

Bulges of disk galaxies at intermediate redshifts. I. Samples with and without bulges in the Groth Strip Survey

L. Dominguez-Palmero, M. Balcells, P. Erwin +4

We aim to define a sample of intermediate-z disk galaxies harbouring central bulges, and a complementary sample of disk galaxies without measurable bulges. We intend to provide col…

On the buildup of massive early-type galaxies at z<~1. I- Reconciling their hierarchical assembly with mass-downsizing

M. C. Eliche-Moral, M. Prieto, J. Gallego +6

Several studies have tried to ascertain whether or not the increase in abundance of the early-type galaxies (E-S0a's) with time is mainly due to major mergers, reaching opposite co…

The nature of luminous X-ray sources with mid-infrared counterparts

A. Alonso-Herrero, P. G. Perez-Gonzalez, J. Rigby +28

We investigate the luminous X-ray sources in the Lockman Hole (LH) and the Extended Groth Strip (EGS) detected at 24microns using MIPS and also with IRAC on board Spitzer. We assem…

The WIRCam Ultra Deep Survey (WUDS) I. Survey overview and UV luminosity functions at z~5 and z~6

R. Pello, P. Hudelot, N. Laporte +17

The aim of this paper is to introduce the WIRCam Ultra Deep Survey (WUDS), a near-IR photometric public survey carried out at the CFH Telescope in the field of the CFHTLS-D3 field…

A minor merger origin for stellar inner discs and rings in spiral galaxies

M. C. Eliche-Moral, A. C. González-García, M. Balcells +4

Recent observations show that inner discs and rings (IDs and IRs, henceforth) are not preferably found in barred galaxies, a fact that points to the relevance of formation mechanis…

astro-ph.CO2010

On the buildup of massive early-type galaxies at z<~1. II- The coordinated key role of wet, mixed, and dry major mergers

M. C. Eliche-Moral, M. Prieto, J. Gallego +1

Hierarchical models predict that present-day massive early-type galaxies (mETGs) have finished their assembly at a quite late cosmic epoch (z~0.5), conflicting directly with galaxy…

On the nature of the extragalactic number counts in the K-band

G. Barro, J. Gallego, P. G. Pérez-González +10

We investigate the causes of the different shape of the -band number counts when compared to other bands, analyzing in detail the presence of a change in the slope around $K\sim…
