Halpha line profile asymmetries and the chromospheric flare velocity field
D. Kuridze, M. Mathioudakis, P. J. A. Simões +9
The asymmetries observed in the line profiles of solar flares can provide important diagnostics of the properties and dynamics of the flaring atmosphere. In this paper the evolutio…
The astrometric Gaia-FUN-SSO observation campaign of 99 942 Apophis

Astrometric observations performed by the Gaia Follow-Up Network for Solar System Objects (Gaia-FUN-SSO) play a key role in ensuring that moving objects first detected by ESA's Gai…
Coherent Radio Emission from Pulsars
Dipanjan Mitra, G. Melikidze, Janusz Gil
We review a physical model where the high brightness temperature of 10 K observed in pulsar radio emission is explained by coherent curvature radiation excited in th…
First NuSTAR Observations of Mrk 501 within a Radio to TeV Multi-Instrument Campaign

We report on simultaneous broadband observations of the TeV-emitting blazar Markarian 501 between 1 April and 10 August 2013, including the first detailed characterization of the s…
Long term lightcurve of the BL Lac object 1ES 0229+200 at TeV energies
Gabriele Cologna, Mahmoud Mohamed, Stefan J. Wagner +3
The high-frequency peaked BL Lac object 1ES 0229+200 (z = 0.14) was first detected in very high energy (VHE, E > 100 GeV) -rays by the H.E.S.S. (High Energy Stereoscopic System)…
The WEBT campaign on the BL Lac object PG 1553+113 in 2013. An analysis of the enigmatic synchrotron emission
C. M. Raiteri, A. Stamerra, M. Villata +2
A multifrequency campaign on the BL Lac object PG 1553+113 was organized by the Whole Earth Blazar Telescope (WEBT) in 2013 April-August, involving 19 optical, two near-IR, and thr…
The clustering of galaxies in the SDSS-III Baryon Oscillation Spectroscopic Survey: Modeling the clustering and halo occupation distribution of BOSS-CMASS galaxies in the Final Data Release
Sergio A. Rodríguez-Torres, Chia-Hsun Chuang, Francisco Prada +21
We present a study of the clustering and halo occupation distribution of BOSS CMASS galaxies in the redshift range 0.43 < z < 0.7 drawn from the Final SDSS-III Data Release. We com…
The clustering of galaxies in the SDSS-III Baryon Oscillation Spectroscopic Survey: RSD measurement from the LOS-dependent power spectrum of DR12 BOSS galaxies
Héctor Gil-Marín, Will J. Percival, Joel R. Brownstein +13
We measure and analyse the clustering of the Baryon Oscillation Spectroscopic Survey (BOSS) relative to the line-of-sight (LOS), for LOWZ and CMASS galaxy samples drawn from the fi…
Estimating the power spectrum covariance matrix with fewer mock samples
David W. Pearson, Lado Samushia
The covariance matrices of power-spectrum (P(k)) measurements from galaxy surveys are difficult to compute theoretically. The current best practice is to estimate covariance matric…
Dynamics of a solar prominence tornado observed by SDO/AIA on 2012 November 7-8
I. Mghebrishvili, T. V. Zaqarashvili, V. Kukhianidze +4
We study the detailed dynamics of a solar prominence tornado using time series of 171, 304, 193 and 211 Å spectral lines obtained by Solar Dynamics Observatory/ Atmospheric Imaging…
Planetesimal formation in self-gravitating discs -- dust trapping by vortices
P. G. Gibbons, G. R. Mamatsashvili, W. K. M. Rice
The mechanism through which meter-sized boulders grow to km-sized planetesimals in protoplanetary discs is a subject of active research, since it is critical for planet formation.…
Optical and Radio Variability of BL Lacertae
Haritma Gaur, Alok C. Gupta, R. Bachev +17
We observed the prototype blazar, BL Lacertae, extensively in optical and radio bands during an active phase in the period 2010--2013 when the source showed several prominent outbu…
Discovery of a Highly Polarized Optical Microflare in the Blazar S5 0716+714 During 2014 WEBT Campaign
Gopal Bhatta, Arti Goyal, Michal Ostrowski +42
The occurrence of low-amplitude flux variations in blazars on hourly timescales, commonly known as microvariability, is still a widely debated subject in high-energy astrophysics.…
