Discovery of New Transients

Barbary et al.

SCP06F6

Repeating Survey Programs MAXI (Monitor of All-sky X-ray Imager) -- cover 0.5-30 keV -- Scan the 80%-95% sky every 92 minutes.

PTF (Palomar Transient Factory) -- 1.28m telescope with FOV~7.78 deg2

-- 5 days cadence (40%), 0.5 day cadence (41%) -- cover 1000 deg2/night -- g’, r’ filters

Pan-STARRS -- 1.8m telescope with FOV~ 7 deg2

-- 3 pi survey with 7 days cadence -- cover 60000 deg2/night -- g’,r’,I’,z’ filters

Rau et al. 2009

Objects we plan to study

1. Core-Collapse supernovae (Ib,Ic, and II)

2. X-ray flashes discovered by the Swift/XRT and the MAXI (e.g. 2008D)

3. Optical transients discovered by PS1 and PTF

4. X-ray transients discovered by MAXI

Our StrategiesA. Supernovae -- Long term monitoring (days to year) -- Multi-band observations -- Cadence : 1-2 days or longer coverage for each SN B. X-ray flashes -- Need quick response -- High time resolution monitoring , multi-band -- Cadence : 1-5 days after the discovery

C. Transients found by PS1 and MAXI -- long term monitoring (days to months) -- multi-band monitoring -- Cadence : observe everyday for selected targets

Scientific topics

1. Investigate the connection between GRBs and supernovae

2. Systematic study on physical parameters of CCSNe( e.g. distribution of Ni mass, kinetic energy of the explosions)

3. Make CCSNe photometric templates for

investigating high-z SNe.

4. Identify optical counterparts for x-ray transients.

5. Study temporal evolution of new types of transients.

Experience from GRB follow-up

1. More than 22 refereed papers were published

2. Circulated more than 110 GCN Circular.

3. Four students got PHD with EAFON data.

The EAFON results

We need similar network for photometric and spectroscopic

observations Photometric program

-- Lulin 1-m telescope (ToO, 2010 Feb.)

-- Maidanak 1.5m telescope (planning)

Spectroscopic program

-- BOAO 1.8m telescope (PI program, 2010 Jan.)

-- Xinglong 2m telescope (planning)

With Maidanak 1.5m telescope Stable weather (especially in summer) and

good seeing.

Good image quality (Maidanak1.5m+SNUCCD, pix =0.266”, Lulin 1m+PICCD, pix ~ 0.56”)

High-QE in U (~50%) and I (~90%) filters

Service mode

Lulin 1m + Maidanak 1.5mA. Supernovae -- Long term monitoring (days to year) -- Multi-band observations -- Cadence : 1-2 days or longer coverage for each SN B. X-ray flashes -- Need quick response -- High time resolution monitoring , multi-band -- Cadence : 1-5 days after the discovery

C. Transients found by PS1 and MAXI -- long term monitoring (days to months) -- multi-band monitoring -- Cadence : observe everyday for selected targets

SN2009kf discovered by PS1

Summary

1.We plan to study temporal evolution of

transients with small telescopes.

2.With experience on EAFON, we could

build similar network for transient study.

3.The program started with Lulin 1-m this year.

4.Our next step is building same program with Maidanak 1.5 m telescope.
