Acceleration in Fast Halo CMEs and Synchronized Flare HXR Bursts (2008, background): “Therefore, it is important to identify CME structures in on-disk coronal images (see studies by Hudson et al. 1996; Dere et al. 1997; Alexander et al. 2002; Gallagher et al. 2003; Uralov et al. 2005; Vršnak et al. 2006; Dauphin et al. 2006).”
Energy partition in two solar flare/CME events (2004, methodology): “[8] Coronal mass ejections for both the 21 April 2002 and 23 July 2002 events were well observed by both the LASCO C2 and C3 coronagraphs [Brueckner et al., 1995] on SOHO [Domingo et al., 1995] (Figure 2). A detailed analysis of the propagation of the 21 April CME through the corona as observed by T”
COMBINED STEREO/RHESSI STUDY OF CORONAL MASS EJECTION ACCELERATION AND PARTICLE ACCELERATION IN SOLAR FLARES (2010, methodology): “Based on the formulas given in Gallagher et al. (2003), we generate synthetic kinematical curves of CME propagation representing different scenarios of CME evolution (impulsive and gradual acceleration profiles).”
Sixty-five years of solar radioastronomy: flares, coronal mass ejections and Sun–Earth connection (2008, background): “The detection of rising UV and soft X-ray loops in the low corona and at the onset of CMEs by Gallagher et al. (2003) and Dauphin et al. (2006) provides further arguments in favour of an association between the CME acceleration and the particle acceleration phases.”
A Statistical Study of Main and Residual Accelerations of Coronal Mass Ejections (2006, background): “This kind of temporal coincidence between flare and CME, or CME-related-ejecta (e.g., filaments), has also been shown bymany other studies (Gallagher et al. 2003; Shanmugaraju et al. 2003; Qiu et al. 2004; Maricic et al. 2004; Kundu et al. 2004; Sterling & Moore 2005; Jing et al. 2005) To further…”
Magnetic Reconnection and Mass Acceleration in Flare-Coronal Mass Ejection Events (2004, result): “…light curves and the time derivative of the soft X-ray light 3 For more information, see: http://cdaw.gsfc.nasa.gov/CME_list/. curve to infer the evolution of the magnetic reconnection rate, as in previous studies (Zhang et al. 2001; Gallagher et al. 2003; Cheng et al. 2003; Wang et al. 2003).”
Topological Evolution of a Fast Magnetic Breakout CME in Three Dimensions (2008, background): “…measured an erupting filament peak acceleration of 3000 m s 2, St. Cyr et al. (1999) observed a peak acceleration of 3270 m s 2, and Alexander et al. (2002) and Gallagher et al. (2003) found erupting X-ray and EUV features having maximum acceleration on the order of k1000 m s 2, respectively.”

Eruption of a Kink-unstable Filament in NOAA Active Region 10696 (2005, unknown): “Furthermore, the filament eruption itself appears to follow an exponentially growing form (cf. Gallagher et al. 2003; Shanmugaraju et al. 2003), suggestive of an instability.”
On the Magnetic Flux Budget in Low-Corona Magnetic Reconnection and Interplanetary Coronal Mass Ejections (2007, background): “…C1-C2-C3 data have demonstrated that the timing relationship between flares and fast CMEs is much closer than previously thought (Zhang et al. 2001; Gallagher et al. 2003; Cheng et al. 2003;Wang et al. 2003; Vrsnak et al. 2005), and the latest studies further illustrate a temporal correlation and…”
