## Five new outbursting AM CVn systems discovered by the Palomar Transient Factory

We present five new outbursting AM CVn systems and one candidate discovered as part of an ongoing search for such systems using the Palomar Transient Factory (PTF). This is the first large- area, systematic search for AM CVn systems using only large- …

## PTF10iya: a short-lived, luminous flare from the nuclear region of a star-forming galaxy

We present the discovery and characterization of PTF10iya, a short-lived (Δt≈ 10 d, with an optical decay rate of ̃0.3 mag d$^-1$), luminous (? mag) transient source found by the Palomar Transient Factory. The ultraviolet/optical spectral energy …
